Objective: To assess the prevalence and clustering patterns of cardiometabolic risk factors among low-income, female adolescents. Materials and methods: Cross-sectional study involving 196 students of public schools (11-19 years old). The following risk factors were considered in the analysis: excess weight, central obesity, dyslipidemia, high blood pressure, and high fasting glucose. The ratio between observed and expected prevalence and its confidence interval were used to identify clustering of risk factors that exceeded expected prevalence in the population. Results: The most prevalent risk factors were dyslipidemia (70.9%), and central obesity (39.8%), followed by excess weight (29.6%), and high blood pressure (12.8%). A total of 42.9% of adolescents had two or more risk factors, and 24% had three or more. Excess weight, central obesity, and dyslipidemia were common risk factors in the clustering patterns that showed higher-than-expected prevalence. Conclusions: Clustering of risk factors (≥ two factors) among the adolescents showed considerable prevalence, and there was a non-casual coexistence of excess weight, central obesity, and dyslipidemia (mainly low HDL-cholesterol).

Objective To analyze the prevalence of metabolic syndrome (MS) in pubertal stages of female students. Methods Cross-sectional study of 449 school children between eight and 18 years, stratified by pubertal stage, body mass index (BMI) and body fat percentage (BF %). The MS was classified according to the International Diabetes Federation. The analysis by frequency distribution, confidence intervals (95 %), Chi-square and odds ratio for associations was performed. Results The prevalence of MS was 3.3 % (CI:2 %-5 %) and 2.5 % (CI: 0.1 - 5 %) in pubertal and 7.9% (CI:3.2 % - 12.6 %) in the post-pubescent, with a significant association of this group with MS (X² = 5.2 [p <0.02]). The odds ratio shows that post-pubescent girls (3.3 [CI: 1.2 to 5]) and obese girls (2.1 [CI: 2 - 2.2]) are more likely to have MS, indicating significant linear association between BMI and the outcome (X²=29.4 [p<0.001]). Pubescent children under 10 years of age with MS had higher %G. The prevalent components were altered waist circumference (27.2 % [CI23 %-31 %]) and low HDL cholesterol (39.6 % [CI 35 % - 44 %]), as well as prevalence of systemic hypertension in post-pubertal girls. Conclusions MS begins in the pubertal stage, with prevalence in the post-pubertal stage. Excess fat is a trigger in children under 10 years of age. Prevention strategies are needed for the population of children and adolescents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
