Maternal prepregnancy body mass index and gestational weight gain on offspring overweight in early infancy.

ABSTRACT:

Objective

The aim of the present study was to evaluate the association of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) with anthropometry in the offspring from birth to 12 months old in Tianjin, China.

Methods

Between 2009 and 2011, health care records of 38,539 pregnant women had been collected, and their children had been measured body weight and length at birth, 3, 6, 9 and 12 months of age. The independent and joint associations of pre-pregnancy BMI and GWG based on the Institute of Medicine (IOM) guidelines with anthropometry in the offspring were examined using General Linear Model and Logistic Regression.

Results

Prepregnancy BMI and maternal GWG were positively associated with Z-scores for birth weight-for-gestational age, birth length-for-gestational age, and birth weight-for-length. Infants born to mothers with excessive GWG had the greatest changes in Z-scores for weight-for-age from birth to Month 3, and from Month 6 to Month 12, and the greatest changes in Z-scores for length-for-age from birth to months 3 and 12 compared with infants born to mothers with adequate GWG. Excessive GWG was associated with an increased risk of offspring overweight or obesity at 12 months old in all BMI categories except underweight.

Conclusions

Maternal prepregnancy overweight/obesity and excessive GWG were associated with greater weight gain and length gain of offspring in early infancy. Excessive GWG was associated with increased infancy overweight and obesity risk.

Project description:OBJECTIVE:To study the association of prepregnancy body mass index (BMI) and gestational weight gain with child neurodevelopmental outcomes. METHODS:We performed a secondary analysis of data from two parallel, multicenter, randomized, double-blind, placebo-controlled thyroxine replacement trials in pregnant women with either hypothyroxinemia or subclinical hypothyroidism who delivered at term. Body mass index was categorized as normal (18.5-24.9), overweight (25.0-29.9), or obese (30 or greater). We also evaluated early (20 weeks of gestation or less), late (greater than 20 weeks of gestation), and total gestational weight gain and categorized gestational weight gain as inadequate, adequate, and excessive per 2009 Institute of Medicine guidelines. Neurodevelopmental outcomes included 5-year Wechsler Preschool and Primary Scale of Intelligence and 3-year Differential Ability Scales-II. Linear and logistic regression analyses were performed and adjusted for maternal age, race-ethnicity, education, insurance status, parity, smoking and alcohol use, thyroid status (subclinical hypothyroidism or hypothyroxinemia), treatment group, gestational age at delivery, and neonatal sex. RESULTS:Of the 948 women included, 380 (40%), 305 (32%), and 263 (28%) had normal, overweight, and obese prepregnancy BMI, respectively. A total of 106 (11%), 212 (22%), and 630 (66%) of women had inadequate, adequate, and excessive total rates of gestational weight gain, respectively. Maternal differences among the BMI categories included race-ethnicity, education, insurance type, parity, and thyroid status (all P<.01), whereas the gestational weight gain groups only differed by parity (P<.001). In unadjusted analysis, children of obese (93.2±12.8; 88.5±13.3) and overweight (94.1±15.6; 89.6±16.0) women had lower Wechsler Preschool and Primary Scale of Intelligence and Differential Ability Scales-II scores, respectively, than normal-weight women (97.4±15.4; 93.9±16.0; P<.001 for all comparisons); however, in adjusted analysis, there were no differences in neurodevelopmental outcomes by maternal BMI. The association was primarily accounted for by race-ethnicity and education. In unadjusted and adjusted analyses, there were no differences in neurodevelopmental outcomes by adequacy of early, late, or total gestational weight gain. CONCLUSION:In women with either subclinical hypothyroidism or hypothyroxinemia, neither prepregnancy BMI nor gestational weight gain was associated with neurodevelopmental outcomes among children born at term in adjusted analyses.

Project description:ImportanceInformation on the association between maternal prepregnancy body weight, gestational weight change, and childhood allergies is not consistent. Little is known on whether there is a combined association with comprehensive childhood allergies.ObjectiveTo examine the association of maternal prepregnancy body mass index and gestational weight gain (GWG) with the risk of childhood allergic diseases including asthma and/or wheezing, allergic rhinitis, eczema, and food and/or drug allergy.Design, setting, and participantsThis cross-sectional study was conducted from April 12 to June 1, 2019, using the Shanghai Children Allergy Study (SCAS), a large, population-based survey. A multistage and multistrata sampling approach was applied to conduct the survey in 13 districts across Shanghai, China, with an enrollment of 15 145 mother-child pairs.ExposuresReported maternal weight before pregnancy and at the time of delivery were requested in the survey; GWG was examined in absolute terms and with reference to the Institute of Medicine guideline.Main outcomes and measuresThe ascertainment of allergic diseases was based on the International Study of Asthma and Allergies in Childhood questionnaire.ResultsAmong 15 145 children aged 3 to 14 years (7911 [52.2%] boys) within the SCAS, 8877 children (58.6%) were screened for allergic diseases. Multivariable log-binomial regression models suggested that excessive GWG was associated with risks of 19% for asthma/wheezing, 11% for allergic rhinitis, and 10% for eczema in the children. Gestational weight gain extremely above the Institute of Medicine guideline in women who were overweight/obese before pregnancy was associated with the highest risk of childhood asthma/wheezing (adjusted prevalence ratio, 1.42; 95% CI, 1.16-1.74; P = .001), allergic rhinitis (adjusted prevalence ratio, 1.32; 95% CI, 1.12-1.56; P = .001), and eczema (adjusted prevalence ratio, 1.24; 95% CI, 1.08-1.41; P = .002). Gestational weight gain below the Institute of Medicine guideline was associated with an attenuated risk of 13% for childhood asthma/wheezing, 11% for allergic rhinitis, 14% for eczema, and 15% food/drug allergy when mothers were of prepregnancy normal weight; similar associations were observed in underweight mothers, but there was no association in overweight mothers. Generally, the associations were similar in the stratified analysis according to children's age group. Moreover, the results were similar in the allergen test subgroup.Conclusions and relevanceThe findings of this study suggest that excessive GWG may be a risk factor for childhood allergic diseases. Further studies on the long-term effects of the intrauterine environment on children's health may take maternal weight management during pregnancy into consideration since GWG could be a controllable and modifiable risk factor.
