Abstract Background Previous studies reported that poor sleep quality (PSQ) was associated with musculoskeletal pains (MSP) and poor physical performance in athletes. Objective The current study aimed at determining PSQ and its associations with MSP in some sub-Saharan athletes. Methods A cross sectional study was conducted among 205 highly trained and 115 elite athletes (aged: 25 ± 2 years, Body mass index: 22.8 ± 0.9 kg/m2) in Dakar, Senegal, during a competitive season in a variety of sport disciplines including athletics, basketball, football, rugby, wrestling, tennis. Quality of sleep and MSP were assessed using the French version Pittsburgh Sleep Quality Index (PSQI) and French version of Nordic questionnaire respectively. Pain on body joints during a week was defined as seven-day MSP (MSP-7d) and PSQ for a PSQI > 5. Results 27.8% (95%CI: 23.2–32.9) of the overall sample suffered PSQ, with 33.7% (95%CI: 24.7–44.0) in basketball and 24.7% (95%CI: 16.9–34.6) in football. According to athletic status and gender, PSQ was more prevalent among highly trained (66.3; 95%CI: 55.9–75.3) and men (69.7%; 95%CI: 59.5–78.7). Among athletes with PSQ 43.8% (95%CI: 33.9–54.2) suffered MSP-7d, with 36.6%; highly trained (95%CI: 23.7–42.9) and 28.1% female. Considering body region, hips/thigh (14.6%; 95% CI: 8.74–23.4) and upper back (13.5%; 95%CI: 7.88 -21, 1) were more affected. Basketball players were more affected from MSP (MSP-7d = 38.5%; 95%CI: 24. 9–54.1) on high on wrists/hands (MSP-7d = 44.4%; 95%CI: 18.9 -73.3; P = 0.04). Based on athletic status, MSP-7d were higher on highly trained necks (100%; 95%CI: 56.1–100; p = 0.04). PSQ was associated with basketball (OR: 3.062, 95%CI: 1.130–8.300, p = 0.02) compared to Athletic. PSQ and MSP-7d were associated on Wrist/hands (OR: 3.352, 95%CI: 1.235–9.099, p = 0.01), and at the upper back (OR: 5.820, 95%CI: 2.096–16.161, p = 0.0007). Conclusion These results indicate that PSQ is considerable among Senegalese athletes and is associated with MSP during a week. Hence, we recommend to look for strategies optimizing good quality of sleep in order to reduce pains, to improve health.

The COVID-19 pandemic has highlighted the challenges of vaccination and the infectious risks among the elderlies. However, immunization rates for recommended vaccines in this population are insufficient in France. We aimed in this study to identify the levers and obstacles to vaccination among seniors, and to establish the arguments that could lead to some new vaccination behaviors. A qualitative survey based on 14 semi-structured interviews was conducted with people aged 65 and over, living at home in the Auvergne Rhône-Alpes region (France) from March to May 2022. The interviews were recorded, entirely transcribed, then subjected to a thematic content analysis. The results show that participants are keen to preserve their health by maintaining their physical capacity, taking regular exercise and eating a balanced diet. However, vaccination was not mentioned as a mean of preventing infectious diseases. Infections were not perceived as a cause for concern. Furthermore, the physical and cognitive consequences of infectious diseases, which could result in a loss of autonomy, were not known. These elements could be a good lever to bring hesitant elderly people to reconsider their position toward vaccination. Vaccines were not seen as a strategy to prevent loss of autonomy among elderlies. Since vaccines against influenza, COVID-19, shingles, pneumococcus have proved to be effective in protecting against cardiovascular events, this argument might be the starting point for a prevention campaign for the elderly.

Introduction Africa is experiencing a gradual demographic shift due to rising life expectancy and increasing urbanisation. In sub-Saharan Africa, elderly individuals typically reside with their children. The rise in life expectancy by almost a decade and the prevalence of precarious living conditions raise concerns about the sustainability of the healthcare system, which has traditionally relied on intergenerational solidarity.Methods The research aims to analyse the evolving role of older adults in Cameroonian society and to examine the potential impact of this change on intergenerational relationships and the health of older adults. A qualitative methodology was employed, using intergenerational focus groups in Cameroon.Results Traditionally, older adults held a central role in knowledge transmission through discourse. However, the modernisation of society is challenging this position.The emergence of new technologies, particularly communication tools, is leading to a questioning of older adults’ experiential knowledge. Societal changes are contributing to a decline in respect for older adults in discourse. Older adults deplore these societal changes and fear for their place in society while young people are questioning the central role of older people in society.Discussion These changes could reduce the sense of usefulness of older people, with negative consequences for their health. Several studies have highlighted the impacts of ageism on the health of older adults in industrialised countries. However, there are little data on the impact of the marginalisation of older adults on their health in industrialising societies. Further research is needed to study the impact on the health of older adults.

The 800-m (m) run is part of Physical Education classes in Cameroon, after which arrhythmias may occur during recovery. Hence, this study aimed at determining relationship between 800-m run loads on cardiac autonomic recovery among school adolescents.Forty-two male adolescents (aged [17 ​± ​1] years) performed 800-m. Post-exercise heart rate variability (HRV) was recorded during 5-min (min) (HRV5-min) and 15-min (HRV15-min) in time: Standard deviation of normal to normal (SDNN); Root mean square of successive differences (RMSSD) and frequency domain (LH: Low frequency, HF: High frequency, TP: Total power). Rating of Perceived Exertion (RPE) and blood lactate concentration (BLa) were measured after exercise. In HRV5-min, RPE was associated with SDNN (r ​= ​−0.44, p ​

Abstract Background The Emergency unit of the hospital (Department) (ED) is the fastest and most common way for most French general practitioners (GPs) to respond to the complexity of managing older adults patients with multiple chronic diseases. In 2013, French regional health authorities proposed to set up telephone hotlines to promote interactions between GP clinics and hospitals. The main objective of our study was to analyze whether the hotlines and solutions proposed by the responding geriatrician reduced the number of hospital admissions, and more specifically the number of emergency room admissions. Methods We conducted a multicenter observational study from April 2018 to April 2020 at seven French investigative sites. A questionnaire was completed by all hotline physicians after each call. Results The study population consisted of 4,137 individuals who met the inclusion and exclusion criteria. Of the 4,137 phone calls received by the participants, 64.2% (n = 2 657) were requests for advice, and 35.8% (n = 1,480) were requests for emergency hospitalization. Of the 1,480 phone calls for emergency hospitalization, 285 calls resulted in hospital admission in the emergency room (19.3%), and 658 calls in the geriatric short stay (44.5%). Of the 2,657 calls for advice/consultation/delayed hospitalization, 9.7% were also duplicated by emergency hospital admission. Conclusion This study revealed the value of hotlines in guiding the care of older adults. The results showed the potential effectiveness of hotlines in preventing unnecessary hospital admissions or in identifying cases requiring hospital admission in the emergency room. Hotlines can help improve the care pathway for older adults and pave the way for future progress. Trial registration Registered under Clinical Trial Number NCT03959475.

Objectives: Burnout syndrome (BOS) is an affection mostly resulting from chronic job-related stress. Many studies have identified job-related and non-job-related factors associated with BOS. Our aim of this study was to assess the level of BOS in private and public hospital healthcare providers in Fako division, Cameroon and evaluate the impact of physical activity and sleep quality (SQ). Methods: The study was carried out in five randomly selected hospitals in Fako Division over a three-month period. Consenting doctors, nurses and laboratory technicians were recruited using consecutive sampling methods. Sociodemographic and professional characteristics were collected using a structured questionnaire. BOS was assessed using the Maslach Burnout Inventory Human Services Survey (MBI-HSS). Sleep quality (SQ) and physical activity (PA) were assessed using the Pittsburgh Sleep Quality Index (PSQI) and Global Physical Activity Questionnaire (GPAQ) respectively. Odd ratios and 95% confidence intervals were calculated and a statistical significance was set for p-value < 0.05. Results: The mean age was 32 ± 6 years and 70.9% female. BOS prevalence was 66.3% with 71.4% in females and 53.9% in males (p = 0.002). Of the 232 participants with BOS, 65.7%, 52% and 53.7% had moderate to high emotional exhaustion, depersonalization and decreased personal accomplishment, respectively. Moderate to high PA as well as poor SQ were not significantly associated with BOS while longer sleep duration (>8 h) was associated with a greater odd of BOS. Conclusions: The prevalence of BOS was high among healthcare professionals. While PA showed no protective effects, high sleep duration could increase its risk.

Abstract Background Living areas in developing countries impact seriously lifestyle by modifying energy consumption and energy expenditure. Thus, urbanization is associated with less practice of physical activity (PA), a leading cause of metabolic syndrome (MetS) which prevalence vary in African countries. The present study aimed to assess the effect of PA on MetS according to urbanization level in the littoral region, Cameroon. Methods A cross-sectional study was conducted in three geographical settings (urban, semi-urban, and rural) in the littoral region in Cameroon. A total of 879 participants were included (urban: 372, semi-urban: 195 and rural: 312). MetS was defined according to the International Federation of Diabetes 2009. The level of PA was assessed using the Global Physical Activity questionnaire. Results Low level of PA was (P

BackgroundAlthough the health benefits of physical activity (PA) are recognized, prostate cancer patients do not follow PA recommendations. Barriers to PA, whether physical, environmental or organizational, are known. Furthermore, even when these barriers are overcome, this achievement is not systematically accompanied by lifestyle change. Many strategies have shown to be effective in increasing patient adherence to PA. This study aims to assess the feasibility and the viability of the Acti-Pair program which combines three strategies: peer support, a personalized and realistic PA project, and support from health and adapted physical activity professionals in a local context.Methods and analysisWe conducted a pilot study utilizing a mixed qualitative and quantitative methodology, employing feasibility and viability assessments. Quantitative assessments included recruitment, retention adherence rates, process and potential effectiveness (PA and motivation) indicators; while qualitative methods were used to evaluate the program's practicality, suitability and usefulness. Indicators of potential effectiveness were assessed before and after the intervention using a Wilcoxon test for matched data. Qualitative data were collected through semistructured interviews conducted by two researchers with various program stakeholders. The study lasted for 3 years.ResultsTwenty-four patients were recruited over a 25-month period. Forty-two percent of patients completed the program 3 months after the beginning. We recruited 14 peers and trained nine peers over a 10-month period. The program was coordinated extensively by adapted PA professionals, while health professionals were involved in recruiting patients and peers. Self-reporting of moderate to vigorous PA was increased after the Acti-Pair program initiation [42.86 (30.76) at baseline to 53.29 (50.73)]. Intrinsic motivation significantly increased after participation in the Acti-Pair program [1.76 (1.32) before the intervention vs. 2.91 (1.13) after the intervention]. The key player to support the Acti-Pair program in the field has been the PA support system. The main challenge has been the difficulty of health professionals in promoting PA.DiscussionThis pilot study has shown that the Acti-Pair program is feasible and viable. It will allow us to extend the peer support intervention to other contexts and assess the effectiveness of this intervention and its generalization.

While the burden of metabolic syndrome (MetS)is still increasing in sub-Saharan Africa, there is a lack of data among young Cameroonian population. The aim of this study was to evaluate the prevalence of MetS and its components among secondary school students in Douala.This was a cross-sectional prospective study carried out on 803 students recruited from February to May 2021 in public and private secondary schools in Douala city, Cameroon. MetS was assessed according to the IDF/AHA/NHLBI 2009 consensus definition. The data collection consisted of a questionnaire on sociodemographic characteristics, measurement of anthropometric parameters (height, weight, body massindex (BMI), waist circumference) and overnight fasting blood sample. Blood pressure (BP), fasting blood glucose,HDL cholesterol and triglycerides were measured using standard methods. The mean age was 18±3 years, 73.3% female. The prevalence of MetS was 27.4%, common among participants aged ≥16 years, and higher in females compare to males (33.7% vs. 11.1%, P0.0001). The prevalence of MetS components i.e abdominal obesity, high BP, fasting hyperglycemia, low-level HDL cholesterol and hypertriglyceridemia were 14.1, 18.1, 42.8, 51.4 and 38.6% respectively. All MetS components were significantly higher in females compared to males except for high BP which was similar among the genders. In our study population, the prevalence of MetS is high and this calls for improved monitoring to limit the evolution of associated cardiometabolic complications among young Cameroonians.

Abstract Background Musculoskeletal pains (MSPs) in sport are cause of poor performances and loss of competition in athletes. The present study aimed at determining the prevalence of MSPs with regard to sport disciplines and athletic status. Methods A cross-sectional study was conducted among 320 Senegalese professional and amateur athletes practicing football, basketball, rugby, tennis, athletics, and wrestling. Rates of MSPs in the past year (MSPs-12) and week (MSPs-7d) were assessed using standard questionnaires. Results Overall proportions of MSPs-12 and MSPs-7d were 70 and 74.2%, respectively. MSPs-12 were more frequently reported on shoulders (40.6%), neck (37.1%) and hips/thigh (34.4%), while MSPs-7d were predominant on hips/thigh (29.5%), shoulders (25.7%), and upper back (17.2%). Proportions of MSPs-12 and MSPs-7d varied significantly by sport disciplines, with highest values among basketball players. Again, highest MSPs-12 proportions on shoulders (29.7%, P = 0.02), wrists/hands (34.6%, P = 0.001), (40.2%, P = 0.0002), and knees (38.8%, P = 0.002) were seen among basketball players. High proportions of MSPs-7d were seen on shoulders (29.6%, P = 0.04) for tennis players, wrists/hands (29.4%, P = 0.03) for basketball and football players, and hips/thigh (38.8%, P

Abstract Background Musculoskeletal Disorders (MSDs) are very common conditions in the workplace. Among professional drivers, there would be an increased risk of developing these disorders. Identifying the associated factors would allow us to better devise effective prevention strategies. Our objective was to determine the prevalence of MSDs among taxi drivers in the city of Yaoundé and to search for associated factors, mainly the level of physical activity. Methods We conducted an analytical cross-sectional study of 151 adult male professional taxi drivers. We used a non-probabilistic consecutive and non-exhaustive sampling method. Sociodemographic, anthropometric and occupational data were collected. MSDs over the past 12 months were assessed using the Nordic Questionnaire and physical activity level was determined by the World Health Organization (WHO) Global Physical Activity Questionnaire (GPAQ). Univariate logistic regression models, followed by a multivariate logistic regression, were used to determine factors associated with the presence of MSDs. Results The overall prevalence of MSDs was 86.8% (95% CI 80.8 – 91.4); the most affected areas were mainly the lower back (72.8%) the neck (42.4%), and the knees (29.1%). Job dissatisfaction was associated with MSDs (OR = 2.1 95%CI = 1.1–3.9). Most taxi drivers (62.9%) had a low physical activity level and no association was found between the physical activity level and MSDs. Conclusions MSDs are common ailments among taxi drivers in Yaoundé (Cameroon). There is a need to think about how to address job dissatisfaction and better identify other associated factors in order to define good prevention strategies.

Background: The issue of excessively heavy schoolbags remains a public health concern in Africa. This study aimed to determine the weight of schoolbags among students in the public and private sectors of Yaoundé city, Cameroon and identify factors associated with low back pain.Methods: A cross-sectional study was conducted during the first term of the 2020/2021 academic year in French-speaking private and public primary schools in Yaoundé city, Cameroon. The study involved 2000 pupils (8.41±2.11 years), with 1000 from the public sector and 1000 from the private sector. The variables analyzed included weight, height, and schoolbag weight. A questionnaire, developed specifically for this study and based on the Standardized Nordic Body Map Questionnaire, was used to collect socio-demographic information and assess potential musculoskeletal low back pain. A diagram was included to indicate the lower back area for reporting pain. The questionnaire was administered, and each student answered it, with assistance from the investigator if needed. Descriptive and inferential statistics, as well as multiple logistic regressions, were employed for data analysis.Results: The average weight of the children and their schoolbags was 28.51±8.04 kg and 4.04±1.72 kg, respectively. Nearly 45% of the pupils were carrying a schoolbag weighing more than 15% of their body weight, and 23% reported experiencing low back pain. Schoolbag weights ranging from 10-15% of body weight were associated with a threefold higher risk (OR=2.66; 95% CI=1.65 – 4.31; P

Introduction: HIV infection has become a chronic disease. Management has shifted to the prevention and treatment of chronic diseases. Regular physical activity (PA) reduces the impact of HIV. Our objectives were to determine levels of PA, assess quality of life (QoL) and determine the degree to which Brief WHOQOLHIV domains and PA influence QoL in older PLHIV. Methods: We conducted a cross-sectional study between March 2020 and March 2021 among 136 older PLHIV at Mvog Ada District Hospital in Yaoundé. Two questionnaires were administered to assess the level of PA (Ricci and Gagnon) and the brief WHOQOL HIV. A bivariate and multivariate analyses were performed. Result: The mean age of the participants was 57.07 ± 6.7 years and the female/male ratio was 1.6. Physical inactivity was found in 56.60% of the participants; 43.40% of them felt they had a good quality of life and 65.40% had a good health status. The environmental domain and social relationship had low scores compared to the spiritual domain and the level of independence. Scores for the different domains were higher in active participants than in inactive participants; with the psychological domain more related to physical inactivity (p

BackgroundIt is well documented that moderate-to-vigorous intensity physical activity (MVPA) is effective in the prevention of major chronic diseases. Even though the current international physical activity (PA) guidelines still mainly focus on MVPA, the topic of the most recent epidemiological studies has shifted from MVPA to light intensity physical activity (LPA), owing to the necessity of promoting all activities vs. sedentary behavior (SB). However, the evidence remains currently limited. Thus, the clarification of the effects of LPA and the close relationship with SB is crucial to promote public health.MethodPA and SB were assessed by a validated self-administered questionnaire (POPAQ) investigating 5 different types of PA during the 7 previous days. PA was measured in metabolic equivalent of task (MET)-h, which refers to the amount of energy (calories) expended per hour of PA. SB was measured in hour/day. Medical histories and examinations were taken during each clinical visit to determine clinical events. All-cause mortality was established using the same procedure and by checking local death registries. The relationships between the intensity of PA (light, moderate to vigorous) and mortality and between the periods of SB and mortality or CV events were analyzed by splines and COX models, adjusted for sex and year of birth.ResultsFrom the 1011 65-year-old subjects initially included in 2001 (60% women), the last 18-year follow-up has been currently completed since 2019. A total of 197 deaths (19.2%, including 77 CV deaths) and 195 CV events (19.3%) were reported. Averages (standard deviation) of MVPA, LPA and SB were, respectively, 1.2 h/d (0.3), 5.8 h/d (1.1), and 6.6 h/d (2.3). For all-cause deaths, as well as CV deaths, the splines were significant for LPA (p = 0.04 and p = 0.01), and MVPA (p

Background: Increasing the longevity of people living with HIV (PLHIV) around the world has been accompanied by an increase in the prevalence of cardiovascular disease (CVD) risk factors and morbidity. The impact of these trends on the epidemiology of CVD among PLHIV is less clear. The aim of this study was to assess the risk factors for CVD, and to estimate these risks at 10 years in PLHIV aged 50 and above. Methods: This was a descriptive and analytical study carried out at Mvog Ada District Hospital in Yaounde, Cameroon from January 2020 to January 2021. Descriptive bivariate analyses were used to present the data. The data are presented as frequencies and percentages for categorical variables, and in terms of means and standard deviations for continuous variables where appropriate. The 10-year CVD risk score was calculated using two tools: the validated Framingham risk score (FRS) (low < 10%, moderate 10–20% and high ≥ 20%) and SCORE score (SSC) (low < 3%, moderate 3–4% and high ≥ 5%). Multiple logistic regression models were constructed to examine the respective relationships between the binary dependent variable high CVD risk (FRS ≥ 20%) and the population group, alcohol consumption (more than 10 glasses of beer per week, or more than 35.7 cl/day) and hypertriglyceridemia (independent variables). A p-value less than or equal to 0.05 was considered statistically significant. Results: A total of 112 people aged 50 and above were enrolled in the study out of 180 people registered at the HIV care unit, that is a participation rate of 62.22%. The average age of the participants was 57.3 ± 6.4 years, and the female/male ratio was 1.6. The majority of participants (53.57%) had normal glycaemia levels (

Background: Physical fitness in Cameroonian students has been assessed previously, but most have focused on urban areas. This study aimed to objectively evaluate two components of physical fitness and factors associated with it among urban and semiurban secondary school students in two municipalities in the Littoral province, Cameroon.Methods: A cross-sectional study was conducted between January and April 2021 in three randomly selected secondary schools in the Littoral Province. The study included 459 students aged 10 to 15 years, comprising 252 students from urban areas (UA) and 207 from semi-urban areas (SUA). Each student’s height, weight, and blood pressure were assessed, and two field tests (20-m shuttle test and 4x10-m test) were performed to estimate maximal oxygen uptake (VO2max) and measure agility. Descriptive and inferential statistics were used for data analysis.Results: The overall prevalence of overweight/obesity was 21.4%, with a higher prevalence of overweight/obesity among boys in semi-urban areas and an equal prevalence of overweight among urban and semi-urban girls. SUA students performed significantly better in the speed test (4x10-m) and VO2max (P

IntroductionMusculoskeletal disorders (MSDs) represent an important threat to public health in both developed and developing countries, and are present in many occupational sectors including education. Regular practice of physical activity (PA) is known elicit preventive effects on the occurrence of MSDs.ObjectiveThis study aimed at determining the prevalence of MSDs and the preventive impact of PA on their occurrence among secondary school teachers.Participants and MethodsA cross-sectional study was conducted among 179 teachers in five government secondary schools in Douala, Cameroon. The Nordic and Ricci-Gagnon questionnaires were used to determine MSDs and to assess the level of PA, respectively.ResultsThe 12-month and 7-day prevalence of MSD (PMSD-12m and PMSD-7d) were 84.3% and 69.3%, respectively. The most affected body regions by MSDs were neck (PMSD-12m = 54.2%, PMSD-7d = 33.5%), lower back (PMSD-12m = 43%, PMSD-7d = 33%), and shoulders (PMSD-12m = 35%, PMSD-7d = 22.9%). Compared to female, males were protected against MSDs during the last 12 months (OR = 0.37; 95% CI 0.16–0.93; p = 0.04). The risk of MSDs during the last seven days was higher in teachers aged 30-40 years (OR = 2.86; 95% CI 1.14–7.14; p = 0.02) and 40-50 years (OR = 4.28; 95% CI 1.49–16.29; p = 0.008) than those under 30 years. This risk was tripled in inactive teachers (OR = 3.07; 95% CI 1.40–6.78; p = 0.005), compared to their active counterparts.ConclusionMSDs are prevalent among secondary school teachers and associated with aging, gender, and lower level of PA

High serum cholesterol is a risk factor for cardiovascular disease (CVD), leading to many fatalities. Traditional palm wine (Elaeis guineensis) and corn beer are noted as potential sources of probiotic bacteria with cholesterol lowering activity. In this study, we isolated and characterised lactic acid bacteria (LAB) with probiotic and cholesterol lowering properties from these sources. The isolates were identified using API 50 CHL kit and sequencing of 16 S rRNA gene. A hypercholesterolemia model involving three groups of eighteen diet-induced Wistar albino rats was established, and the serum lipid profile was analysed using biochemical kits. The genotypic identification of two best cholesterol lowering LAB revealed that they were strains of Levilactobacillus brevis and Enterococcus faeccium. Their 16 S r RNA gene sequences were deposited in NCBI genbank with the accension numbers ON454506 and ON908682 respectively. These isolates effectively lowered LDL-c and increased HDL-c in rat sera, which are the main risk factors for CVD. These probiotics are potential candidates for functional foods formulation against hypercholesterolemia.

Abstract Background Falls are a significant source of morbidity in people aged 65 and over, affecting one in three people in this age group. The scientific evidence indicates that physical activity is the most effective method for preventing falls among seniors. Although public health professionals often use social marketing to design and plan successful interventions, its use to promote physical activity and prevent falls among older people remains low. This article aims to provide a new systematic literature review of social marketing interventions promoting physical activity and targeting people aged 60 and over. Methods Following CRD’s guidance and PRISMA guidelines, we searched between January 2008 and July 2019 for relevant articles in five primary databases using predefined search and inclusion criteria. Two independent reviewers analysed the selected articles to identify evidence of the seven social marketing benchmark criteria, defined by experts in the field as the common elements that contribute to social marketing success. Results The final review included nine studies. Of the studies selected, three specifically targeted over 60-year-olds, whereas the others segmented the population into several age-based subcategories, including over 60-year-olds. Eight studies highlighted positive results for the participants with an increase in participation or an increase in physical activity level. None of the nine studies selected for this systematic review implemented the entire social marketing approach. Conclusion Few published interventions use the seven social marketing criteria. Further research is required to encourage uptake and inclusion in successful social marketing interventions to increase program effectiveness in this target population.

Abstract Background Physical activity may decrease the risk of dementia; however, previous cohort studies seldom investigated the different types of physical activity and household activities. Our objective was to analyze the links between two physical activity types and dementia in older people. Methods The study used data from the prospective observational Three-city cohort and included 1550 community-dwelling individuals aged 72 to 87 without dementia at baseline. Physical activity was assessed with the Voorrips questionnaire. Two sub-scores were calculated to assess household/transportation activities and leisure/sport activities. Restricted cubic spline and proportional hazard Cox models were used to estimate the non-linear exposure-response curve for the dementia risk and the appropriate activity level thresholds. Models were adjusted for possible confounders, including socio-demographic variables, comorbidities, depressive symptoms and APOE genotype. Results The median age was 80 years, and 63.6% of participants were women. After a median follow-up of 4.6 years, dementia was diagnosed in 117 participants (7.6%). An inverse J-shaped association was found between household/transportation physical activity sub-score and dementia risk, which means that the risk is lowest for the moderately high values and then re-increases slightly for the highest values. The results remained significant when this sub-score was categorized in three classes (low, moderate, and high), with hazard ratios (95% confidence interval) of 0.55 (0.35–0.87) and 0.62 (0.38–1.01) for moderate and high activity levels, respectively. No significant effect was found for leisure/sport activities. Conclusions The 5-year risk of dementia was significantly and negatively associated with the household/transportation activity level, but not with the leisure and sport activity sub-score. This highlights the importance of considering all physical activity types in 72 years or older people.

Background: Falls affects one of three people after 65 years old, and it can lead to serious consequences. Scientific evidence point out that physical exercise is the most efficient way to prevent falls among older adults.Objective: The main objective of this study is to determine if a social marketing program can increase the attendance rate of people aged 60 and over at group balance workshops.Methods: This quasi-experimental multicenter study is being conducted in three French Regions (Loire, Haute-Loire and Rhône) over a period of 18 months. The Social Marketing Campaign will be done in three ways. Firstly, a Communication Campaign will take place in the two Test Areas but not in the Control Area. Secondly, flyers have been designed to be distributed by local partners. Finally, conferences for older people will be organized in the areas of intervention in order to reach the target audience for the program. The study will include people aged 60 and older who want to participate in the Balance Program.Results: The Crédit Agricole Loire/Haute-Loire Foundation funded the study and the Jean Monnet University of Saint-Etienne reviewed it. The Ethics Committee of the University Teaching Hospital of Saint-Etienne approved and peer-reviewed it on September 6, 2019, under Reference Number IRBN622019/CHUSTE.Conclusion: The results of this first study will demonstrate whether or not social marketing for promoting group balance workshops in the elderly will increase their attendanceship in adapted physical activity sessions, especially those that prevent falls.Clinical Trial Registration:https://clinicaltrials.gov/ct2/show/NCT04136938, identifier NCT04136938.

In February 2021, France had more than 76,000 deaths due to COVID-19 and older adults were heavily affected. Most measures taken to reduce the impact of COVID-19 (quarantine, visit ban in nursing home, etc.) significantly influenced the lives of older adults. Yet they were rarely consulted about their implementation. Exclusion of and discrimination against older adults has been accentuated during the COVID-19 pandemic. While many articles discussing COVID-19 also mention ageism, few actually incorporate the perspectives and opinions of older adults. Our research aims to assess the ageism experienced by older adults during the COVID-19 pandemic. We conducted interviews with older adults (63–92 years, mean age = 76 years) in an urban area of France. Participants reported experiencing more ageism during the COVID-19 pandemic, including hostile and benevolent ageism from older adults' families. Despite reports of experiencing ageist attitudes and behaviors from others, however, older adults also identified positive signs of intergenerational solidarity during this COVID-19 crisis.

Several studies suggest that physical activity improves cognitive functions and reduces cognitive decline, whereas others did not find any evidence of a neuroprotective effect. Furthermore, few cohort studies have analyzed the different physical activity types and particularly household activities. Our objective was to assess the association of two physical activity types with the decline in different cognitive domains in a large prospective cohort of community-dwelling older adults from the Three-city study. Physical activity (domestic/transportation activities and leisure/sport activities) was assessed with the Voorrips questionnaire, specific for older adults. Baseline sociodemographic and health history variables as well as cognitive performance data at baseline and during the 8-year follow-up (Mini-Mental State Examination, Benton Visual Retention Test, Trail Making Tests A and B, Isaac's Set Test and Free and Cued Selective Reminding Test) were also available. Associations between physical activity scores and cognitive decline in different domains were tested using minimally- and multi-adjusted linear mixed models. The analysis included 1697 participants without dementia at baseline and with at least one follow-up visit. At baseline, participants with higher sub-scores for the two physical activity types had better cognitive performances. Interaction with time showed that decline in some cognitive scores (Trail Making Test B and Isaac's Set Test) was significantly less pronounced in participants with higher household/transportation activity sub-scores. No significant effect over time was found for leisure/sport activities. This study shows that during an 8-year follow-up, executive functions and verbal fluency were better preserved in older adults who performed household/transportation activities at moderate to high level. Participation in domestic activities and using adapted transport means could allow older adults to maintain specific cognitive abilities.

Background: Previous cohorts studied the association of various types of physical activities with the incidence of cognitive disorders. The objective of this work was to analyze the association of leisure, domestic and professional physical activities with mild and moderate cognitive disorders in older people living in the community.Methods: We used retrospective data from the “FRéLE” (FRagilité: étude Longitudinale de ses Expressions) a longitudinal and observational study. Data collected included socio-demographic variables, lifestyle and health status. Cognitive disorders were assessed using the Montreal Cognitive Assessment (MoCA). Two cut-offs of MoCA were used to analyze mild and moderate cognitive disorders. Physical activity was assessed by the Physical Activity Scale for the Elderly (PASE) structured in three sections: leisure, household, and professional activities. Spline and logistic regression models were used to estimate the risk of cognitive disorders.Results: At baseline, 428 participants (for study of mild disorders) and 1,271 participants (for study of moderate disorders) without cognitive disorders were included in the analysis. The mean ages were 74 and 78 years, respectively. After a 2-year follow-up, we found mild cognitive disorders in 154 participants (36%) and 71 cases of moderate cognitive disorders (5.6%). In multi-adjusted logistic models, domestic activities were associated with cognitive disorders, but not leisure and professional activities.Conclusion: We found an inverse relation between domestic sub-score and cognitive disorders defined by MoCA < 18. With a specific questionnaire and quantitative information on the type of activities, this study contributed to the debate on the beneficial effects of physical activity on cognition.

Abstract Background This study compares the performance of four frailty screening tools in predicting relevant adverse outcome (disability, institutionalization and mortality) in community-dwelling elderly. Methods Our study involved a secondary analysis of data from the FréLE cohort study. We focused on the following four frailty screening tools: the abbreviated Comprehensive Geriatric Assessment (aCGA), the Groningen Frailty Indicator (GFI), the Vulnerable Elders Survey-13 (VES-13) and the Fried scale. We used the Barberger-Gateau scale to assess disability. For comparison, we determined the capacity of these tools to predict the occurrence of disability, institutionalization or death using the receiver operating characteristic (ROC) curve. We also determined the threshold at which an optimal balance between sensitivity and specificity was reached. Odds ratios (ORs) were calculated to compare the risk of adverse outcome in the frail versus non-frail groups. Results In total, 1643 participants were included in the mortality analyses; 1224 participants were included in the analyses of the other outcomes (74.5% of the original sample). The mean age was 77.7 years, and 48.1% of the participants were women. The prevalence of frailty in this sample ranged from 15.0% (Fried) to 52.2% (VES-13). According to the Barberger-Gateau scale, 643 (52.5%) participants were fully independent; 392 (32.0%) were mildly disabled; 118 (9.6%) were moderately disabled; and 71 (5.8%) were severely disabled. The tool with the greatest sensitivity for predicting the occurrence of disability, mortality and institutionalization was VES-13, which showed sensitivities of 91.0%, 89.7% and 92.3%, respectively. The values for the area under the curve (AUC) of the four screening tools at the proposed cut-off points ranged from 0.63 to 0.75. The odds (univariate and multivariate analysis) of developing a disability were significantly greater among the elderly identified as being frail by all four tools. Conclusion The multivariate analyses showed that the VES-13 may predict the occurrence of disability, mortality and institutionalization. However, the AUC analysis showed that even this tool did not have good discriminatory ability. These findings suggest that despite the high number of frailty screening tools described in the literature, there is still a need for a screening tool with high predictive performance.

Background: Work may contribute significantly to daily physical activity (PA) and sedentary behavior (SB). Physical inactivity and SB at work might be two major risk factors for premature morbidity. Therefore, the aim of this research was to describe self-reported past PA and SB at work and during leisure time within the PROOF cohort subjects, and to determine consequences of PA and SB on late health of these now retired workers.Material and Methods: The PROOF cohort study was used to prospectively allow assessment of the predictive value of PA and SB at work and during leisure time among a healthy retired French population, with regard to cardiovascular and cerebrovascular events. PA (MET-h/week) and SB (h/d) were assessed using the Population Physical Activity Questionnaire (POPAQ) and the modified Global Physical Activity Questionnaire (GPAQ). Odds ratios (ORs with 95% CIs) for cardiovascular and cerebrovascular events were associated with each level of PA at work: light (

To assess the association between periodontal diseases and cardiovascular diseases in dental patients in Cameroon, a prospective observational study was carried out in 3 hospitals in Cameroon from January 2013 to December 2015. Data on general condition, age, gender and lifestyle were collected during medical history taking. The Dutch Periodontal Screening Index assessed periodontal health during oral examination. The Wilcoxon test, the Fisher test and logistic regression analysis were performed. 558 patients (53.9% women) were included in the study. The mean age was 44±13 years (30 to 85). In terms of overall health, 161 (28.9%) had cardiovascular diseases (CVD) and 73 (13.1%) had diabetes. Hypertension accounted for 87.6% of CVD. In terms of periodontal diseases (PD), 431 (77.2%) patients had PD, the break-down by PD was 347 (62.2%) gingivitis and 84 (15%) periodontitis. Statistical associations were found between CVD and gingivitis [OR=4.30 (1.85-10.00), P=0.001], and CVD and periodontitis [OR=2.87 (1.04-7.93); P=0.04].
