AbstractThe association between dietary patterns and metabolic cardiovascular risk factors has long been addressed but there is a lack of evidence towards the effects of the overall diet on the complex net of biological inter-relationships between risk factors. This study aimed to derive dietary patterns and examine their associations with metabolic cardiovascular risk factors following a theoretic model for the relationship between them. Participants included 417 adults of both sexes, enrolled to the cross-sectional population-based study performed in Brazil. Body weight, waist circumference, high-sensitivity C-reactive protein, blood pressure, total cholesterol:HDL-cholesterol ratio, TAG:HDL-cholesterol ratio, fasting plasma glucose and serum leptin were evaluated. Food consumption was assessed by two non-consecutive 24-h dietary recalls adjusted for the within-person variation of intake. A total of three dietary patterns were derived by exploratory structural equation modelling: ‘Traditional’, ‘Prudent’ and ‘Modern’. The ‘Traditional’ pattern had a negative and direct effect on obesity indicators (serum LEP, body weight and waist circumference) and negative indirect effects on total cholesterol:HDL-cholesterol ratio, TAG:HDL-cholesterol ratio and fasting plasma glucose. The ‘Prudent’ pattern had a negative and direct effect on systolic blood pressure. No association was observed for the ‘Modern’ pattern and metabolic risk factors. In conclusion, the ‘Traditional’ and ‘Prudent’ dietary patterns were negatively associated with metabolic cardiovascular risk factors among Brazilian adults. Their apparent protective effects against obesity and high blood pressure may be important non-pharmacological strategies for the prevention and control of obesity-related metabolic disorders and CVD.

Background:This study aimed to examine combined and independent effects of cardiorespiratory fitness and fatness on cardiovascular risk factors among U.S. adolescents.Methods:Data from adolescents age 12 to 19 years participating in the NHANES 1999 to 2002 were used. Fitness level was determined by submaximal treadmill test and was dichotomized as ‘not fit’ or ‘fit’ according to the FITNESSGRAM. Fatness level was categorized as ‘not fat’ or ‘fat’ based on the CDC BMI growth charts. Gender-specific multivariable linear regression analyses were conducted to compare age-, race/ethnicity-, fatness-, and waist circumference-adjusted means of blood pressure, lipids, lipoproteins, C-peptide, insulin, and C-reactive protein (CRP) levels.Results:A total of 3202 adolescents (1629 boys) were included for data analysis. Among boys, total cholesterol, tri-glycerides, insulin, and CRP mean levels were significantly higher (P < .05) in the ‘not fit’ group than in the ‘fit’ group, after adjustment for fatness level and waist circumference. Among girls, the fatness level- and waist circumference-adjusted means of total cholesterol (P < .01) and LDL-C (P < .09) were higher in the ‘not fit’ than ‘fit’ groups.Conclusion:Cardiorespiratory fitness, independent of fatness, may have beneficial effects on lipid profiles among girls, and on lipid profiles, insulin metabolism, and inflammation levels among boys.

ABSTRACTObjectiveThe objective of this study is to determine the prevalence of abdominal obesity and its associated factors in Burkina Faso. We hypothesize that there is a high burden of abdominal obesity and it is significantly associated with sociodemographic and cardiovascular risk factors.DesignWe performed secondary analysis of the survey conducted in Burkina Faso using the World Health Organization (WHO) STEPwise approach.SettingThe study was conducted in Burkina Faso with all 13 regions of the country included.ParticipantsOur study involved 4308 adults of both sexes aged 25 to 64 years.Main outcomeOur primary outcome was the abdominal obesity which was could defined using a cut-off point of waist circumference (WC) of ≥94 cm for men and ≥80 cm for women.ResultsThe overall age-standardized prevalence of abdominal obesity was 22.5% (95% CI: 21.3–23.7). This age-standardized prevalence was 35.9% (95% CI: 33.9–37.9) among women and 5.2% (95% CI: 4.3–6.2) among men (p < 0.001). In urban areas, the age-standardized prevalence of abdominal obesity was 42.8% (95% CI: 39.9–45.7) and 17.0% (95%CI: 15.7–18.2) in rural areas (p < 0.001). The overall age-standardized prevalence of very high WC (WC ≥102 cm for men and ≥88 cm for women) was 10.2% (95%CI: 9.3–11.1). According to the National Institute for Health and Clinical Excellence (NICE) BMI–WC matrix, which combines the body mass index (BMI) and WC to define different levels of cardiovascular health risk, 14.6% of adult Burkinabè had an increased cardiovascular health risk.ConclusionOur study shows a high prevalence of abdominal obesity among the adult population in Burkina Faso. These findings suggest that the measurement of WC should be systematically incorporated in Burkina Faso primary healthcare centers for the early detection of high cardiovascular risk in order to reduce levels of premature death.STRENGTHS AND LIMITATIONS OF THIS STUDY➢This is the first national representative study on abdominal obesity in the context of an emerging epidemiological transition in Burkina Faso.➢A recommended cut-off point was used to define abdominal obesity among the adult population in Burkina Faso, which we found to be associated with “intermediate” cardiovascular risk factors.➢The waist circumference and risk factors used in this study were measured using the standard approach proposed by the WHO [1]. However, some risk factors such as physical inactivity, alcohol consumption, and type of fat were self-reported and may therefore be affected by information bias.➢This study was a cross-sectional study and must not be considered to make causal inference.Target journalhttps://bmjopen.bmj.com/

Physical activity is an important component of cardiovascular health. The fact that physical activity is also associated with a substantial number of cognitive and academic benefits, therefore schools teachers can be an important role model in promoting a physically-active lifestyle in school children. The aim of this study is to examine the levels of physical activity (PA) and its association with cardiovascular risk factors in a sample of school teachers. Forty-nine (n=49) teachers from primary and secondary schools around Klang Valley urban areas were recruited. The PA level was determined using pedometer, worn for three consecutive days. Anthropometric measurements and blood samples were collected to determine cardiovascular risk factors. Findings showed that the school teachers recorded an overall mean (± SEM) of 7707 ± 490 steps/day, which is below the recommended target of 10 000 steps per day. According to pedometer-determined physical activity indices proposed by Tudor-Locke and Bassett (2004), 20.83% of the sample were classified as ‘sedentary’ (<5000 steps/day), 35.40% were ‘low active’ (5000 – 7499 steps/day) and only 18.70% achieved more than 10 000 steps/day. According to Asian BMI cut-off points, 43% of the teachers were categorized as overweight and obese (>23 kg/m2). The mean values for waist circumference, fasting blood sugar, and cholesterol level, systolic and diastolic blood pressure were 83.96 ± 1.90 cm, 5.41 ± 0.26 mmol/l, 4.64±0.26 mmol/l, 118.90 ± 1.72 mmHg and 72.40±1.58 mmHg respectively. Fisher Exact Test shown that there were significant association between daily step and age category. Daily steps weakly negative correlated with systolic blood pressure (r = -0.024, p > 0.05) as well as blood sugar levels (r = -0.061, p> 0.05), diastolic blood pressure (r = -0.079, p> 0.05), body mass index (r = -0.271, p> 0.05), waist circumference (r = -0.196, p> 0.05), as well as blood cholesterol levels (r = -0.037, p> 0.05). In conclusion, there were weak negative correlations between steps per day and cardiovascular risk factors. Generally, the level of physical activity in the sample of teachers needs to be improved. Interventions aimed at promoting PA among school teachers may be warranted in the future.
