Relationship between Dyslipidemia, Cultural Factors, and Cardiorespiratory Fitness in Schoolchildren

Abstract

Background The presence of dyslipidemia and behavioral aspects are determinants of cardiovascular risk, especially in childhood and adolescence. Objective To verify possible relationships between dyslipidemia, cultural factors, and cardiorespiratory fitness (CRF) in schoolchildren. Methods This cross-sectional study evaluated a sample of 1,254 children and adolescents between the ages of 7 and 17 from the South of Brazil, 686 of whom were female. Dyslipidemia was defined as increased levels of at least one of the following lipid profile parameters: triglycerides (TG), total cholesterol (TC) and fractions of high (HDL-c) and low-density lipoprotein (LDL-c). Cultural aspects were evaluated by a self-reported questionnaire. Data were analyzed by logistic regression, considering the odds ratios (OR) and confidence intervals (CI) at 95%. Results The results revealed a high prevalence of dyslipidemia (41.9%), which was associated with female sex (OR: 1.56; IC: 1.24-1.96) and overweight/obese status (OR: 1.55; IC: 1.20-2.00). When lipid profile parameters were evaluated separately, high levels of LDL-c were observed to be associated with sedentary school transport (OR: 1.59; IC: 1.20-2.09). Schoolchildren who were overweight/obese had higher chances of elevated levels of TC (OR: 1.40; IC: 1.07-1.84) and TG (OR: 3.21; IC: 1.96-5.26). HDL-c was shown to be related to high television time (OR: 1.59; IC: 1.00-2.54). Conclusion Alterations in lipid parameters are associated with cultural factors, especially those related to sedentary lifestyle and low levels of CRF.

Cardiorespiratory Fitness and Muscular Strength Moderates the Relationship between FNDC5 Polymorphism and Adiposity in Children and Adolescents

“…Another important effect of physical exercise is the increase in cardiorespiratory fitness (CRF) and muscular strength, the most studied components of physical fitness, which are considered important health indicators in all ages [ 9 , 10 ]. CRF and muscular strength are inversely associated with adiposity and exert a protective role against the development of cardiometabolic risk factors in children and adolescents [ 11 , 12 ]. Since physical activity and exercise improves CRF, it is plausible that the effects of CRF are mediated by irisin [ 8 ].…”

Home Physical Activity Programs for Children and Adolescents as a Healthy Strategy During Social Isolation Caused by COVID-19: viewpoint

“…7 Given these factors, intervention programs that include physical activity could minimize anxiety and stress, and they could play an important role in preventing weight gain, dyslipidemia, and cardiovascular events. 8,9 The importance of physical exercise is well evidenced in the literature; however, under conditions of social isolation, children and adolescents cannot exercise in other spaces with face-to-face guidance from a qualified professional (e.g., at the school, club, or gym). However, it is relevant to mention that home-based training programs and exercise routines could also be effective for children and adolescents, 9 as it increases levels of physical activity, and consequently, improves the quality of life of those involved.…”
