This study aimed to identify the association of recommended dairy intake with several dietary habits, obesity, physical fitness (PF), physical activity (PA), screen time and sleep. Population data were derived from a health survey on a representative sample of 177 091 children aged 8–17 years. Dairy intake and dietary habits were evaluated using questionnaires (KIDMED index). Participants were characterised as 'dairy products consumers' based on whether they met current recommendations for milk or dairy consumption (e.g. if they consumed two yogurts and/or 40 g cheese and a cup of milk daily). Participants who did not consume the above-mentioned quantities were characterised as 'non-consumers.' Anthropometric and PF data were obtained by trained investigators. PA status, screen time and sleeping habits were assessed through self-completed questionnaires. Boys and girls consuming recommended dairy products were 25 % (95 % CI: 0·71, 0·79) and 43 % (95 % CI: 0·51, 0·64) less likely to have low performances in cardiorespiratory fitness tests, Participants from both sexes classified as dairy products consumers had lower odds of central obesity by 10 % (95 % CI: 0·86, 0·95), as compared with non-consumers. Moreover, recommended dairy products consumers had lower odds for insufficient sleep by 8 % (95 % CI: 0·89, 0·96) in boys and 14 % (95 % CI: 0·83–0·90) in girls, for inadequate PA levels by 15 % (95 % CI: 0·77, 0·93) in boys and 16 % (95 % CI: 0·76, 0·90) in girls and for increased screen time by 11 % (95 % CI: 0·83, 0·95) in boys and 9 % (95 % CI: 0·85, 0·97) in girls than no-consumers. In conclusion, recommended dairy intake is associated with less obesity, better PF and a healthier lifestyle profile. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study was to determine the associations between recreational screen time and dietary habits and lifestyle factors in a representative sample of schoolchildren.Methods: Observational, cross-sectional study data were derived from 177,091 children aged 8 to 17 years participating in a health survey. Recreational screen time, physical activity (PA), and sleeping hours were assessed through self-completed questionnaires. Dietary habits were evaluated via the Mediterranean Diet Quality Index for children and adolescents (KIDMED) test. Anthropometric and physical fitness (PF) estimations were obtained by trained investigators.Results: Binary logistic regression comparisons between screen time levels (e.g. < 2 vs. ≥ 2 - < 3 h/d, < 2 vs. ≥ 3 - < 4 h/d and < 2 vs. ≥ 4 h/d) and dietary habits showed that the longer the screen time the increased the odds of unhealthy dietary habits such as skipping breakfast, consuming fast food frequently, and eating sweets frequently, and the decreased the odds of healthy dietary habits such as consuming a second fruit every day, consuming fresh or cooked vegetables or/and fish regularly, in both genders, after adjusting for several covariates. Furthermore, the longer the screen time the increased the odds of total and central obesity, insufficient sleep (< 8-9 h/d), and inadequate PA, and the decreased the odds of healthy PF.Conclusions: The longer the screen time the unhealthier dietary habits and lifestyle profile among schoolchildren, after adjusting for several covariates.

Aim: The aim of the present study was to examine prevalence and correlates of skipping breakfast in a representative sample of children and adolescents. Methods: Cross‐sectional, observational study. Population data derived from a school‐based health survey carried out in 2015 on 177 091 Greek children aged 8–17 years. Trained investigators performed all anthropometric evaluations. Breakfast skipping and adherence to the Mediterranean diet (MD) was assessed through the Mediterranean Diet Quality Index for children and adolescents. Physical activity status, sedentary activities and sleeping hours were assessed through self‐completed questionnaires. Results: Almost one in four (22.4% of boys, 23.1% of girls) schoolchildren skipped breakfast. Participants' characteristics associated with skipping breakfast were being female, being older, being overweight/obese, poorer diet, inadequate physical activity levels, insufficient sleep and increased screen time. Regression models adjusted for several potential confounders demonstrated that poor dietary habits, insufficient sleeping status (<8–9 hours per day), and increased screen time (>2 hours per day), increased the odds for skipping breakfast by almost 80% (95% CI: 1.78–1.82), 23% (95% CI: 1.20–1.26) and 22.5% (95% CI: 1.19–1.26), respectively. Conclusions: Skipping breakfast was common among schoolchildren. Participants who skipped breakfast tended to have an unhealthy lifestyle profile. Policies designed to increase breakfast consumption should target schoolchildren with unhealthy lifestyle profiles. [ABSTRACT FROM AUTHOR]

This study examined the association between cardiorespiratory fitness (CRF) levels and lifestyle factors in a representative sample of Greek schoolchildren. In 2015, a health survey was carried out in 177 091 participants 8–17 years of age. Dietary habits, sleeping hours, physical activity (PA), and sedentary activities were assessed through self-completed questionnaires. CRF was evaluated with a 20-m shuttle run test. Insufficient dietary habits were greater in boys and girls classified as having low CRF than in their peers with healthy CRF. Skipping breakfast (odds ratio (OR), 0.82; 95% confidence interval (CI) 0.79–0.85), fast food consumption (OR, 0.70; 95% CI 0.68–0.72), and regular sweet intake (OR, 0.79; 95% CI 0.76–0.82) decreased the odds of having a healthy CRF level. An increase in age by 1 year (OR, 0.71; 95% CI, 0.70–0.72), overweight/obesity (OR, 0.30; 95% CI 0.29–0.31), and insufficient sleep duration (OR, 0.74; 95% CI 0.72–0.76) decreased the odds of a healthy CRF level, whereas sufficient dietary habits and adequate PA levels increased a participant's odds of having a healthy CRF level, by 48% and 40%, respectively. Although the mechanisms via which CRF may be influenced by dietary habits remain unclear, health policy-makers should consider opportunities for improving both CRF and dietary habits.

Objective: To examine the prevalence of fast-food consumption and the association between fast food and lifestyle factors in a representative sample of children and adolescents. Design: Cross-sectional, observational study. Fast-food consumption and dietary habits were evaluated using questionnaires (KIDMED index). Anthropometric and physical fitness measurements were obtained by trained investigators. Physical activity (PA) status, sedentary activities and sleeping habits were assessed through self-completed questionnaires. Setting: Greece. Subjects: Population data derived from a school-based health survey (EYZHN programme) carried out in 2015 on 177 091 (51 % boys) children aged 8–17 years. Results: A greater proportion of boys v. girls (23·3 v. 15·7 %, P <0·001) and of adolescents v. children (26·9 v. 17·1 %, P <0·001) reported they consume fast foods >1 time/week. Frequent fast-food consumption was strongly correlated with unhealthy dietary habits such as skipping breakfast and consuming sweets/candy regularly. Adjusting for several covariates, insufficient dietary habits, insufficient (<8–9 h/d) sleep, inadequate PA levels and increased screen time increased the odds (95 % CI) of being a frequent fast-food consumer by 77 % (0·218, 0·234), 30 % (1·270, 1·338), 94 % (1·887, 1·995) and 32 % (1·287, 1·357), respectively. Being overweight/obese or centrally obese did not correlate with frequency of fast-food consumption. Conclusions: Frequent fast-food consumption was associated with an unhealthy lifestyle profile among children and adolescents. The findings support the development of interventions to help children adopt healthier dietary habits. [ABSTRACT FROM AUTHOR]

The aim of the study was to examine the effects of physical activity (PA) level on 10-year cardiovascular disease (CVD) incidence, taking into consideration several clinical and lifestyle risk factors along with the potential moderating role of gender. An analysis was undertaken on data from the ATTICA prospective cohort study (10-year follow-up, 2002-2012), which followed a Greek adult population (aged 18-89years). A total n=317 of fatal and nonfatal CVD events occurred among the 2020 participants. After adjusting for the lifestyle and clinical risk factors as potential confounders, odds ratio (ORs) of CVD risk of individuals who reported being sufficiently active and highly active were decreased by 58% (95% CI: 0.30, 0.58) and 70% (95% CI: 0.15, 0.56), when compared to those who were inactive/insufficiently active, respectively. Men had nearly two-fold increase in risk of CVD (95% CI: 1.62, 2.18) versus women. Stratified analysis by gender, revealed that sufficiently active men, had 52% (95% CI: 0.24, 0.97) reduced risk of CVD incidence when compared to inactive males, while, for women, the role of PA lost significance following adjusting for lifestyle factors. The current data suggests a beneficial effect of even moderate physical activity levels on 10-year incidence of CVD, reinforcing the importance of physically activity, especially for men.
