“…The mid-point of the category selected (i.e., duration) was multiplied by the metabolic equivalent of task (MET) assigned to that activity (i.e., intensity) to arrive at an estimate of volume of physical activity [i.e., (MET ∙ hours) per week]; this proxy for energy expenditure is comparable between individuals of different body weight. MET values for walking and light to moderate-intensity household tasks came from field-based measurements among pregnant women (25); Compendium-based MET values (26) were used for all other activities.…”

Objectives To estimate the associations of moderate and vigorous intensity exercise during pregnancy with the rate of gestational weight gain (GWG) from gestational diabetes (GDM) diagnosis to delivery, overall and stratified by prepregnancy overweight/obesity. Methods Prospective cohort study with physical activity reported shortly after the GDM diagnosis and prepregnancy weight and post-diagnosis GWG obtained from electronic medical records (n= 1,055). Multinomial logistic regression models in the full cohort and stratified by prepregnancy overweight/obesity estimated associations of moderate and vigorous intensity exercise with GWG below and above the Institute of Medicine’s (IOM) prepregnancy BMI-specific recommended ranges for weekly rate of GWG in the second and third trimesters. Results In the full cohort, any participation in vigorous intensity exercise was associated with decreased odds of GWG above recommended ranges as compared to no participation [Odds Ratio (95% Confidence Interval): 0.63 (0.40, 0.99)], with a significant trend for decreasing odds of excess GWG with increasing level of vigorous intensity exercise. Upon stratification by prepregnancy overweight/obesity, significant associations were only observed for BMI ≥ 25.0 kg/m2: any vigorous intensity exercise, as compared to none, was associated with 54% decreased odds of excess GWG [0.46 (0.27, 0.79)] and significant trends were detected for decreasing odds of GWG both below and above the IOM’s recommended ranges with increasing level of vigorous exercise (both P ≤ 0.03). No associations were observed for moderate intensity exercise. Conclusions In women with GDM, particularly overweight and obese women, vigorous intensity exercise during pregnancy may reduce the odds of excess GWG.

“…The Pregnancy Physical Activity Questionnaire is a semi-quantitative questionnaire consisting of 33 questions, two of which are open-ended, that query the frequency and duration of time spent in 4 domains of activity: household/care giving, occupational, sports/exercise, and transportation activities. Activities were assigned MET values according to the compendium of physical activities (17) and where possible, pregnancy-specific MET values (18). MET intensity values are energy expenditure parameters that are assigned to specific activities through objective measures of physical activity (e.g.…”

Objective To examine associations between pregnancy physical activity and neonatal fat mass and fat-free mass, birth weight and small for gestational age (SGA). Methods We analyzed 826 mother-neonate pairs (term births) participating in the longitudinal Healthy Start study. The Pregnancy Physical Activity Questionnaire was used to assess total energy expenditure and meeting American College of Obstetricians and Gynecologists (the College) guidelines for physical activity during early pregnancy, mid-pregnancy and late pregnancy. Models were adjusted for maternal and neonatal characteristics. Results Neonates had mean fat mass of 292.9 grams, fat-free mass of 2,849.8 g, and birth weight of 3,290.7 g. We observed 107 (12.9%) SGA and 30 (3.6%) large-for-gestational age (LGA) births. A significant inverse linear trend between total energy expenditure during late pregnancy and neonatal fat mass (Ptrend = 0.04) was detected. Neonates of mothers in the highest compared to lowest quartile of total energy expenditure during late pregnancy had 41.1 g less fat mass (249.4 vs. 290.5 g; P = 0.03). No significant trend was found with total energy expenditure and neonatal fat-free mass or birth weight. Early-pregnancy and mid-pregnancy total energy expenditure were not associated with neonatal outcomes. No significant trend was observed between late-pregnancy total energy expenditure and SGA (Ptrend = 0.07), but neonates of mothers in the highest compared to the lowest quartile had a 3.0 (95% CI 1.4–6.7) higher likelihood of SGA. Meeting the College’s physical activity guidelines during pregnancy was not associated with differences in neonatal outcomes. Conclusions Increasing levels of late-pregnancy total energy expenditure are associated with decreased neonatal adiposity without significantly reduced neonatal fat-free mass.

“…Participants selected a range of time spent in each activity on 6-point scales (e.g., ranging from never, ½ to almost 1 hour per week, 2 to almost 3 hours per week, etc.). The mid-point of the selected time spent in each activity (i.e., duration) was multiplied by the activity’s metabolic equivalent of task (MET value, i.e., intensity), using either Compendium-based (Ainsworth et al, 2000) or field-based measurements for pregnant women (Roberts, Fragala, Pober, Chasan-Taber, & Freedson, 2002). Results were summed to calculate total activity (MET hours per week), a proxy for energy expenditure comparable across adults differing in body weight.…”

Background Diet and physical activity lifestyle behaviors are modifiable risk factors for type 2 diabetes and are shaped by culture, potentially influencing diabetes health disparities. Objectives We examined whether ethnic identity—the strength of attachment to one’s ethnic group, and a long-standing focus of psychological research—could help account for variations in lifestyle behaviors within a diverse population at high risk for chronic disease. Methods Using data from the Gestational Diabetes’ Effects on Moms trial, this US-based cross-sectional study included 1,463 pregnant women (74% from minority ethnic/racial groups; 46% born outside the US) with gestational diabetes (GDM), a common pregnancy complication conferring high risk for type 2 diabetes after delivery. Mixed linear regression models examined whether ethnic identity is associated with lifestyle behaviors after adjusting for demographic, clinical, and acculturative characteristics (e.g., nativity and length of residence in the US). Results In the overall sample, a one-unit increase in ethnic identity score was significantly associated with 3% greater fiber intake, 4% greater fruit/vegetable intake, 11% greater total activity, and 11% greater walking (p values < .01). Within ethnic/racial groups, a one-unit increase in ethnic identity score was significantly associated with 17% greater fiber intake among Filipina women; 5% lower total caloric intake among non-Hispanic White women; and 40% greater total activity, 35% greater walking, and 8% greater total caloric intake among Latina women (p values ≤ .03). Conclusion Results from this large study suggest that ethnic group attachment is associated with some lifestyle behaviors, independent of acculturation indicators, among young women with GDM who are at high risk for type 2 diabetes. Stronger ethnic identity may promote certain choices known to be associated with reduced risk of type 2 diabetes. Prospective research is needed to clarify the temporal nature of associations between ethnic identity and modifiable diabetes risk factors.
