BackgroundCardiovascular diseases are among the leading causes of mortality and morbidity in sub-Saharan Africa, including Zambia, where cardiovascular diseases account for 8% of the mortality rates. Despite an increasing number of cardiovascular disease-related studies in Zambia, qualitative studies exploring how cardiovascular diseases and their risk factors are understood in the socioeconomic and cultural contexts are still few. This study, therefore, aimed to analyze the beliefs, perceptions, and behaviors related to cardiovascular diseases and their risk factors among the local residents of Zambia.MethodsThis qualitative study was conducted from August to September 2014 among healthy residents aged 40 years and above in a rural community in Mumbwa District. We investigated the beliefs, perceptions, and behaviors related to cardiovascular diseases and their potential risk factors in the sociocultural context of Zambia by conducting in-depth interviews and focus group interviews. Audio-recorded interviews were transcribed and analyzed using thematic analysis with investigator triangulation.ResultsWe conducted 34 in-depth interviews and 6 focus group interviews with 27 males and 40 females. Most participants were aware of the prevalence of cardiovascular diseases around them and correctly identified hypertension, excessive salt, sugar, and cooking oil intakes, poor quality cooking oil, consumption of meat or vegetables contaminated with chemicals, obesity, stress ["thinking too much"], lack of physical exercise, and heredity as potential risk factors of cardiovascular diseases, while smoking and alcohol were mentioned by only a few participants. However, they claimed that many of these risk factors were difficult to avoid due to ingrained taste preferences for high salt and sugar, increasingly busy lives that force them to use cooking oil to reduce preparation time, cultural preference for big body size or fatness, especially for women, stigmatized body image attached to HIV, stressful life or life events related to poverty, and financial barriers to affording quality foods and healthcare services. Limited health screening opportunities and the negative impact of HIV-related stigma on health-seeking behavior also emerged as important risk factors for cardiovascular diseases.ConclusionsThis study revealed that participants are relatively well aware of cardiovascular diseases and their risk factors. However, they engage in high-risk health behaviors, due to ingrained taste preferences, limited knowledge, and unavoidable socioeconomic and cultural circumstances. Results suggest that prevention interventions addressing cardiovascular diseases in rural Zambia should target gaps in knowledge and socioeconomic and cultural barriers.

BackgroundThere has been a global increase in HIV infection in persons 50 years of age and older. This group is at risk for development of chronic illness that may be exacerbated by socio-behavioral risk factors such as smoking, unhealthy alcohol use, and sedentary lifestyle. However, socio-behavioral risk factors in this older HIV infected population are not well described. The current study aims to describe and document factors related to alcohol use, tobacco smoking, and physical exercise in older adults living with HIV (OALHIV).MethodsThis cross-sectional quantitative study was conducted between August and September 2015, and enrolled HIV-infected participants aged 50 years and older from 12 community hospitals in Chiang Mai Province, Northern Thailand.ResultsOf the 364 participants recruited in the study, 57.1% were female, and 67.3% were between 50-59 years of age. Respectively, 15.1%, 59.1%, and 18.7% were current smokers, currently engaged in physical exercises, and reported ever drank alcohol in the past year. 22.1% of those who drank alcohol reported experience of heavy episodic drinking. Male gender was one of the strongest predictors of ever drank alcohol in the past year (AOR, 4.66; CI, 2.28-9.49; P 20,000 Baht: AOR, 5.34; CI, 1.28-22.25; P = 0.021). Lower educational level was associated with decreased odds of physical exercises (no education versus secondary and higher: AOR, 0.22; CI, 0.08-0.55; P = 0.001).ConclusionSmoking and alcohol use is common among OALHIV, with a substantial proportion not engaging in physical exercises. Interventions for OALHIV should particularly target males and those of lower socio-economic status to deter smoking and alcohol use and to promote physical exercises.
