title: [Sleep quality in overweight pregnant women].
abstract: OBJECTIVE
  To compare sleep quality of overweight versus normal weight women in the second and third trimesters of pregnancy.
  
  
  METHODS
  A cross-sectional study involving 223 women with 14 or more weeks of pregnancy, 105 of them overweight (pre-pregnancy body mass index - BMI - ≥25.0 kg/m2) and 118 of normal weight (BMI 18.5-24.9 kg/m2), attending the prenatal care clinic. The Brazilian version of the Pittsburgh Sleep Quality Index (PSQI-BR) questionnaire was used to evaluate sleep quality. The Student t-test and the chi-square test were used to compare differences between groups and a p value <0.05 was considered statistically significant.
  
  
  RESULTS
  Most of the participants (67.7%) were poor sleepers (total score >5); this proportion was significantly higher among overweight (80/105) versus normal weight (67/118) women (76.2 versus 56.8%, p=0,004). During the second trimester, this difference did not reach statistical significance (72.5 versus 53.7%, respectively, p=0.06) but mean total PSQI-BR scores were significantly higher among overweight participants (7.0±3.8 versus 5.5±3.2, p=0.02). In the 2nd trimester, overweight women also had higher scores for sleep latency (1.4±1.0 versus 1.0±0.9, p=0.02) and subjective sleep quality (1.3±0.8 versus 0.8±0.8, p=0.02). In the third trimester, the proportion of women with poor sleep quality was significantly higher in the overweight group, but did not reach statistical significance (79.6 versus 60.8%, p=0.06). During this period, total mean scores were similar for women with and without excess weight (9.4±4.2 versus 8.3±4.6, p=0.2). However, overweight women had higher mean scores for sleep disturbance (2.3±0.7 versus 2.0±0.8, p=0.04).
  
  
  CONCLUSIONS
  Overweight women had a poorer sleep quality than normal weight women in the second and third trimesters of pregnancy.
