Depression and body fat deposition in Mexican pregnant adolescents

Background. The objective of this study was to assess the effect of materna l depressive symptomatology on fat deposition in a group of pregnant adoles cents. Methods. A case-control study was performed with 85 pregnant women (45 adol escents and 40 adults) who attended a prenatal care course at a teaching ho spital in Mexico City. During the second and third trimesters of gestation, a test proposed by Zung was applied to measure depressive symptoms. Weight and skinfolds (i.e., triceps, biceps, suprailiac, subscapular, and thigh) were measured in all women beginning at week 20 of gestation through 4 week s postpartum. Monthly evaluations were performed. Results. At the 28th week of gestation. nearly 40% of pregnant adolescents showed scores above the cut-off points in the depression test. while among the adults this proportion corresponded to 15%. In the adolescents. depress ion status was related to self-esteem Percentage of body fat in adult women tended to be relatively constant, while in adolescents a tendency toward i ncreased body fat was found. In adolescents, depressive symptomatology and especially lack of self-esteem and weight ain during pregnancy were the var iables that better predicted the fat-increment pattern during gestation. wh ile in adults no variable was found that predicted fat deposition. Conclusions. Depression status is a risk factor for excessive fat depositio n during pregnancy in Mexican adolescents. (C) 2000 IMSS. Published by Else vier Science Inc.
