Nível de atividade física, gasto energético e estado nutricional de mulheres residentes em assentamentos subnormais (favelas) de Maceió/Al

Abstract

OBJECTIVE: To assess the level of physical activity of female residents in favelasand their relationship with energy expenditure and nutritional status. METHODS: A cross-sectional study was carried out between April / 2012 and July / 2014, with 84 women with and without short stature. All residents of substandard settlements (favelas) of the 7th. region of the city of Maceió / AL. In these, socioeconomic and anthropometric assessments were carried out. The Physical Activity Level (NAF) was evaluated using the triaxial accelerometer, brand activPAL® (Glasgow, UK) 3TM. The total energy expenditure (GET) and body composition were measured by double-labeled water and food consumption using R24h. The Estimated Energy Requirement (EER) was determined by Mifflin's formula (1990). RESULTS: The sample had a mean age of 32 + 6.29 years. Women with short stature had lower schooling (5.98 years), and had more children (2.88) than women without short stature. The mean BMI of the women was 29.94 kg / m2. The food intake of women of short stature was similar (1847.97 kcal / day) to those of short stature (1868.94 kcal / day). The GET (2014.24 kcal / day) and the EER (1896.70 kcal / day) of the short stature women were smaller than the GET (2292.79 kcal / day) (p = 0.025) and the EER (2177, 99kcal / day) (p <0.001) of women without short stature. In the studied sample the average NAF found per day was 1.5 characterizing activity of light intensity. Women with short stature presented higher NAF (day) (1.51), showing more activity than women without short stature (1.46) (p = 0.001). Women with short stature performed more steps / day (p = 0.004), spent less time (h) sitting or lying down / day (p = 0.018) and more time (h) walking / day (p = 0.006) than women without short. CONCLUSIONS: In the light of the above, the study suggests that women of short stature may have developed adaptive mechanisms of energy conservation, making them, although more active than those without short stature, presenting similar energetic and overweight intake
