Is gestational weight gain associated with offspring obesity at 36 months?

ABSTRACT: OBJECTIVE:We examined the association between gestational weight gain (GWG) and offspring obesity at age 36 months. METHODS:Mother-infant dyads (n?=?609) were followed from a first study visit (mean [standard deviation]: 18.8 [2.7] weeks gestation) to 36 months postpartum. Total GWG over the entire pregnancy was defined as excessive or non-excessive according to the 2009 Institute of Medicine guidelines. Four mutually exclusive categories of excessive or non-excessive GWG across early (conception to first study visit) and late (first study visit to delivery) pregnancy defined GWG pattern. Body mass index (BMI) z-scores ?95th percentile of the 2000 Centers for Disease Control (CDC) references defined offspring obesity at 36 months. Multivariable log-binomial models adjusted for pre-pregnancy BMI and breastfeeding were used to estimate the association between GWG and childhood obesity risk. RESULTS:Nearly half of the women had total excessive GWG. Of these, 46% gained excessively during both early and late pregnancy while 22% gained excessively early and non-excessively late, and the remaining 32% gained non-excess weight early and excessively later. Thirteen per cent of all children were obese at 36 months. Excessive total GWG was associated with more than twice the risk of child obesity (adjusted risk ratio [95% confidence interval]: 2.20 [1.35, 3.61]) compared with overall non-excessive GWG. Compared with a pattern of non-excessive GWG in both early and late pregnancy, excessive GWG in both periods was associated with an increased risk of obesity (2.39 [1.13, 5.08]). CONCLUSIONS:Excessive GWG is a potentially modifiable factor that may influence obesity development in early childhood.

Project description:ObjectiveThis study aimed to compare attendance of nutritional counseling, dietary composition, exercise patterns, and socioeconomic factors among obese women with inappropriate gestational weight gain (iGWG) versus appropriate GWG (aGWG).Study designMedicaid-eligible women receiving prenatal care at a tertiary care center from January 2013 to December 2015 were offered individualized nutritional counseling by a registered dietitian encouraging well-balanced meals and 150 min/wk of exercise. We conducted a prospective case-control study of obese women (body mass index or BMI ≥30) with a singleton gestation with iGWG (<11 or >20 pounds) versus aGWG (11-20 pounds). Dietary intake, activity level, and socioeconomic factors were compared with Chi-square, Fisher's exact, Student's t-test, and Wilcoxon Rank Sum tests as indicated, and odds ratios with 95% confidence intervals were calculated. Multivariate regression analysis for significant variables was performed. A subgroup analysis of women with BMI ≥40 was planned.ResultsA total of 401 women were analyzed: 78% (n = 313) with iGWG and 22% (n = 88) with aGWG. Demographics were similar between groups. Women with iGWG less frequently reported physician reinforcement of counseling and reported more physical inactivity and unemployment; there were no differences in caloric intake or macronutrient profile between groups. Multivariate regression identified physician reinforcement and employment as independent predictors of aGWG. Among women with BMI ≥40 (n = 133), those with iGWG (78%) were less likely to attend counseling, report physician reinforcement of counseling, and have adequate caloric and protein intake when compared with those with aGWG (22%). Activity level and socioeconomic factors were not different between groups.ConclusionPhysician reinforcement of nutritional counseling, greater activity level, and employment are associated with aGWG in women with BMI ≥30, while individualized professional nutritional counseling and dietary modifications were further associated with aGWG in women with BMI ≥40. Thus, greater focus should be placed on enhancing exposure to counseling and altering nutritional and exercise choices to optimize aGWG.Key points· Physician reinforcement of nutritional counseling by a dietitian is crucial for obese women.. · Physical inactivity and unemployment are associated with inappropriate gestational weight gain.. · Nutritional counseling is associated with appropriate gestational weight gain in women with BMI ≥40..

Project description:BackgroundInappropriate gestational weight gain (GWG) has been associated with adverse perinatal events. High rates of GWG have been reported among Hispanic women. Observational studies indicate that dietary and physical activity interventions during the prenatal period may improve maternal and infant health, but very few randomized trials have been conducted among high-risk overweight/obese Hispanic women. Accordingly, we conducted a lifestyle intervention among high-risk pregnant women and evaluated its impact on achieving appropriate GWG and on improving birthweight.MethodsEligible overweight/obese women presenting at the University Hospital in Puerto Rico with a singleton pregnancy before 16 gestational weeks were recruited and randomized to lifestyle intervention (n=15) or control group (n=16). The lifestyle intervention focused on improving physical activity and diet quality and optimizing caloric intake. We evaluated the impact of the lifestyle intervention on achieving appropriate GWG and on infant birthweight. Poisson and linear regression analyses were performed.ResultsThe primary intent to treat analysis showed no significant effect on achievement of appropriate GWG/week through 36 weeks in the intervention group (4/15 women) when compared with the control group (3/16 women) (adjusted incidence rate ratio =1.14; 95% CI: 0.20, 6.67). Although not statistically significant, women in the intervention group (6/15) were 1.7 times more likely to achieve appropriate weekly GWG until delivery when compared with controls (4/16 women) (adjusted incidence rate ratio = 1.67; 95% CI: 0.40, 6.94). We observed lower adjusted birthweight-for-length z-scores in the intervention compared with the control group among male newborns with z-score difference -1.74 (-3.04, -0.43), but not among females -0.83 (-3.85, 2.19). These analyses were adjusted for age and baseline body mass index.ConclusionAlthough larger studies are required to determine whether women with obesity may benefit from prenatal lifestyle interventions targeting GWG, our results are suggestive of the intervention improving adherence to established Institute of Medicine guidelines.
