Perfil antropométrico, nível de atividade física, e comparação da composição corporal por diferentes métodos de avaliação de militares da marinha do Brasil

Abstract

The aim of the study was to assess the nutritional profile and compare the body composition of Brazilian Navy servicemen from the state of Rio Grande do Norte using different investigative methods, as well as assessing their level of physical activity. The sample consisted of 53 male military personnel aged between 25 and 50. Anthropometric measurements of weight, height, waist circumference, as well as biceps, triceps, subscapular, suprailiac, pectoral, abdominal, axillary and medial thigh skinfolds were collected to determine nutritional status and body composition, as well as bioimpedance assessment and recording of physical activity levels. The data was analyzed using SPSS 23.0 software using descriptive analysis, Pearson's correlation of numerical variables and association of categorical variables using Fisher's exact test. There was a predominance of overweight among the soldiers (58.5%), and a 4 greater number of individuals at risk of diseases associated with obesity when body fat was assessed by sum of folds and bioimpedance, with a stronger correlation between the sum of 4 and 7 folds. On the other hand, the average waist circumference was 88.4 cm, which, although within the normal range, is close to the value that corresponds to an increased risk of cardiovascular disease. Although the majority of military personnel are active or very active, the excess weight and risk associated with obesity in this population is worrying, and may be a reflection of a poor quality of life. It is important to carry out more detailed research, especially into the eating habits of these soldiers.
