Basal metabolic rate in pregnant adolescents.

Background & Aims: In most clinical settings basal metabolic rate (BMR) is estimated by predictive equations (PE) but there is no specific algorithm for pregnant women. To this end, this study aimed to measure BMR (BMR) in single-fetus primigravida 63 adolescent pregnant women recruited from primary health care units from a tropical municipality in Brazil. Additionally, BMR was compared with estimated BMR from internationally recommended PE for nonpregnant adolescents.

Seasonal variation in food intake and the interaction effects of sex and age among adults in southern Brazil.

Background/objectives: Because studies have evidenced variations in nutrient intake, further investigation of the interaction between demographic characteristics and the seasons is necessary. We aimed to test the differences in food intake throughout the seasons and the interaction between the seasons and sex and age.

Subjects/methods: This study included 273 individuals.
