Factors associated with insufficient weight gain among Mexican pregnant women with HIV infection receiving antiretroviral therapy.

ABSTRACT: OBJECTIVE:We identified clinical, dietary, and socioeconomic factors associated with insufficient gestational weight gain among Mexican pregnant women with human immunodeficiency virus (HIV) infection. METHODS:This was a cross-sectional study involving 112 pregnant women with HIV infection receiving antiretroviral therapy (ART). Data including viral load, complete blood analysis, and CD4 counts were extracted from medical records. An inquiry form was used to collect data on socioeconomic status and frequency of food intake. Pre-gestational weight was calculated based on pregnancy weight to obtain the body mass index (BMI) and weight gain for gestational age according the US Institute of Medicine. Of the study population, 68.7% were in consensual union, 31.3% were single, and 33.9% belonged to the two lowest socioeconomic strata. The median age and CD4 count were 27 (interquartile range [IQR]: 23-32) years and 418 (IQR: 267-591), respectively. The adequacy of energy was 91.8% (IQR: 74.1-117.7). The median energy intake from protein was 13.5% (IQR: 12.2-14.9) and from lipids, 35.5% (IQR: 31.1-40.3). Pregnant women with gastrointestinal symptoms and CD4 count <350 were seven times more likely to have folate deficiency (odds ratio [OR] 7.8, 95% confidence interval [CI] 1.6-38.1; p = 0.009) and six times more likely to have poor zinc intake (OR 6.7, 95% CI 1.3-36.8; p = 0.014). In all, 42.9% of the pregnant women consumed iron and folic acid supplements and 54.4% consumed multivitamin supplements. Moreover, 45.5% had a normal pre-gestational BMI, 41.1% were classified overweight, and 13.4% had obesity, whereas 62.5% showed insufficient gestational weight gain, and 18.8% experienced weight loss. The variables associated with insufficient weight gain were consensual union (OR 5.3, 95% CI 1.9-15.0; p = 0.002) and belonging to the lowest socioeconomic stratum (E) (OR 3.1, 95% CI 1.0-9.2; p = 0.046). CONCLUSION:Dietary strategies to improve gestational weight gain for Mexican women with HIV infection receiving ART must consider clinical and socioeconomic factors.

Project description:BackgroundPhthalates are endocrine disrupting chemicals that may influence weight status; however, few studies have considered weight gain during pregnancy and subsequent long-term weight changes in women.ObjectiveTo determine associations of prenatal phthalate exposure with maternal weight during pregnancy and through up to seven years post-delivery.MethodsWe analyzed 15 urinary phthalate biomarker concentrations during the 2nd and 3rd trimesters among 874 pregnant women enrolled in the Programming Research in Obesity, Growth Environment and Social Stress Study in Mexico City. We examined three time-specific maternal weight outcomes: gestational weight gain (between 2nd and 3rd trimesters), short-term weight (between 3rd trimester and 12 months post-delivery), and long-term weight (between 18 months and 6-7 years post-delivery). We used Bayesian Kernel Machine Regression (BKMR) to estimate associations for the total phthalate mixture, as well as multivariable linear mixed models for individual phthalate biomarkers.ResultsAs a mixture, 2nd trimester urinary phthalate biomarker concentrations were associated with somewhat lower gestational weight gain between the 2nd and 3rd trimesters (interquartile range, IQR, difference: -0.07 standard deviations, SD; 95% credible interval, CrI: -0.20, 0.06); multivariable regression and BKMR models indicated that this inverse association was primarily driven by mono-2-ethyl-5-carboxypentyl terephthalate (MECPTP). Prenatal (2nd and 3rd trimesters) urinary phthalate mixture concentrations were positively associated with maternal weight change through 12 months postpartum (IQR difference: 0.11 SD; 95% CrI: 0.00, 0.23); these associations persisted from 18 months to 6-7 years follow-up (IQR difference: 0.07 SD; 95% CrI: 0.04, 0.10). Postpartum weight changes were associated with mono-3-carboxypropyl phthalate (MCPP) and MECPTP.ConclusionsPrenatal phthalate exposure was inversely associated with gestational weight gain and positively associated with long-term changes in maternal weight. Further investigation is required to understand how phthalates may influence body composition and whether they contribute to the development of obesity and other cardiometabolic diseases in women.
