RESUMO

INTRODUCTION: Studies on the state of health and nutrition of Mexicans with intellectual disability (ID) including those with Down syndrome (DS), are scarce. OBJECTIVE: To analyze some physiological and social factors associated with the body mass of young people with ID from northern México. METHODS: Body weight, height and other anthropometric values were measured in fifty seven young (17 ± 5 years) participants with ID (DS,16%) and at least one guardian. BMI (kg/m²), somatotype and nutritional status were established by three international standards and total blood glucose, cholesterol & triacylglycerides, were also analyzed. Guardian's socio-economic, household food insecurity and nutrition literacy status were estimated with validated questionnaires by direct interview. RESULTS: Participants with SD were 12 cm smaller but subscapular skinfold (SECPS) was 6 mm thicker than that from other ID participants (p < 0.05). Prevalence of overweight/obesity was 70 and 44%, respectively. Blood biochemicals were similar between groups, but 25% had dyslipidemias. Participant's BMI correlated (p < 0,01) with several anthropometric & adiposity indicators (r = 0,40 a 0,88 ), blood triglycerides (r = 0,48 ) and cholesterol (r = 0,44) and guardians & participants' age (r = 0,35). The spending in food correlated (p < 0.05) with participant's SECPS (r = -0.33). The circumference of the waist, hip, calf and PSECP, 89% of the variance of the BMI explained. CONCLUSION: The body mass of young people with DI from northern Mexico, is strongly related to the degree of body adiposity, dyslipidemias, and some socio-economic factors of their family environment.

RESUMO

The factors responsible for the acute effects of exercise on blood lipids are not well known, and there have been few studies comparing different kinds of exercise in the same population. The concentration of blood lipids was evaluated in this study at the end and at post-24h of two 14km/90min single exercise sessions: continuous exercise (CE) at 44.5+/-5.6% VO(2max) and intermittent exercise (IE) at 39-72% VO(2max), in subjects with high levels of aerobic training. Fourteen male athletes (endurance runners) took part in this study and each completed a 24h dietary record. The O(2) uptake and CO(2) production were recorded, and blood lactate and blood lipids were measured. The results showed that triacylglycerols were not modified by any kind of exercise. Total cholesterol was increased at the end of both exercises: 7.04% for CE (p<0.001) and 4.23% for IE (p=0.001). High-density lipoprotein cholesterol was increased at the end of IE: 11.38% (p=0.03) and low-density lipoprotein cholesterol was increased only at the end of CE: 7.45% (p=0.006). The increase of lipids for CE was negatively correlated with aerobic fitness indicators (heart rate and %HRmax at lactate threshold), and was positively associated with energy expenditure. For IE, %HRmax and lactate were negatively correlated, and the respiratory exchange ratio was positively correlated, with the lipid increase. We conclude that in trained male athletes, a 14km run in 90min induced different changes of lipid profile if the exercise was done continuously or intermittently, and that in CE the extent of these increases was influenced by aerobic fitness.
