The Association Between Body Dissatisfaction and Nutritional Status in Adolescents

Purpose. This study analyzes the association between body dissatisfaction and nutritional status in adolescents. Basic Procedures. The study enrolled 234 boys and 442 girls. Information was collected on body image and anthropometry performed. Nutritional status was stratified into two categories: healthy (BMI: 18.5-25.0 kg/m2) and unhealthy (BMI: <18.5 and >25.0 kg/m2). Body image was coded as satisfied and dissatisfied. Main findings. It was found that 65.5% of adolescents were dissatisfied with their body image. While the girls wished to reduce their body silhouettes (48.4%), the boys wished to increase in size (51.3%). Unhealthy nutritional status was only associated with body dissatisfaction among the girls (95%CI = 1.35-3.43). Overweight girls were 11 times more likely to be dissatisfied with their bodies than normal weight girls. Conclusions. Nutritional status was a determinant factor for body dissatisfaction, primarily among female adolescents, since those whose nutritional status was unhealthy had different levels of dissatisfaction from those with healthy BMI.

Abstract

Purpose. The aim of this study was to verify and analyze the association between anthropometric indicators and serum lipid profiles in adolescents. Methods. The study included 250 adolescents aged 11-17 years from both sexes. The anthropometric variables measured were body weight, height and waist circumference. Body mass index and waist circumference were used to calculate a nutritional status rating (whether normal weight or overweight) and abdominal obesity, respectively. Total cholesterol, high-density lipoproteins, low-density lipoprotein and triglyceride levels were determined by an enzymatic colorimetric method using automatic spectrophotometry and were categorized according to cutoff points established by the III Brazilian Guidelines on Dyslipidemia and Atherosclerosis Prevention from the Brazilian Society of Cardiology. Results. The overweight and abdominal obesity prevalence was found to be 23.6% and 40.0%, respectively. Undesirable total cholesterol, high-density lipoprotein, low-density lipoprotein and triglyceride levels were found in 40.8%, 8.4%, 36.0% and 13.6% of the studied adolescents, respectively. Overweight adolescents were 2.29 (CI 95%, 1.07-4.91) times more likely to have high triglyceride levels, and those with abdominal obesity were 2.47 (CI 95%, 1.14-5.37) times more likely to show high triglyceride levels. Conclusions. A high prevalence of overweight and abdominally obese adolescents, with high levels of serum lipid profiles, were observed. Moreover, overweight and abdominally obese adolescents were more likely to have high triglyceride levels.

Health-Related Physical Fitness and Associated Sociodemographic Factors in Adolescents from a Brazilian State Capital

Purpose. The aim of this study was to investigate the associations between health-related physical fitness and sociodemographic factors in students from a capital city of a Brazilian state. Methods. A cross-sectional study was conducted on 605 students aged 15 to 19 years. Sociodemographic data were collected, including gender, age, education level and family income, and correlated to physical fitness levels. Results. The percentages of students with unhealthy body composition, unhealthy skeletal muscle fitness and aerobic fitness levels were 23.8%, 34.4% and 30.5%, respectively. There was a trend for fewer male adolescents (OR: 0.65; IC95%: 0.42-0.98) to have unhealthy body composition. Students from lower socioeconomic families were less likely to have musculoskeletal unfitness (OR = 0.60; IC95%: 0.41-0.89). In relation to aerobic fitness, male students (OR = 3.86; IC95%: 2.67-5.58) and those aged 17-19 years (RO = 1.49; IC95%: 1.02-2.177) were more likely to be unfit. Conclusions. It is important to encourage young people to take part in sports and physical activities at moderate to vigorous intensities in order to improve their body composition, aerobic capacity and physical fitness.
