Aim:  To determine the body mass index (BMI) and the body composition of fathers-to-be and to compare the findings with those of mothers-to-be during early pregnancy., Methods:  This was a descriptive and comparative study based at a large university teaching hospital. We enrolled men whose partner booked for antenatal care in the first trimester of pregnancy during July 2009. The height and weight of both parents-to-be were measured digitally, and BMI was calculated. The body compositions of the couple were analysed using bioelectrical impedance., Results:  Of 167 fathers-to-be, 14% were obese (BMI > 29.9 kg/m2 ) compared with 16% of mothers-to-be (NS). However, 50% were overweight (BMI 25.0-29.9 kg/m(2) ) compared with 26% of mothers-to-be (P < 0.001). This may be explained, in part, because the men were on average two years older than the women, and in the men, BMI increased with age. The men had a lower overall fat percentage (P < 0.001), but their visceral fat was higher than in the women (P < 0.001)., Conclusion:  Our findings show a high level of obesity in fathers-to-be, which has implications not only for the men themselves but also their families. We suggest that public health interventions directed at obesity during pregnancy should include both parents-to-be., (© 2011 The Authors.

Objective: This longitudinal observational study examined BMI changes between successive pregnancies.Methods: The computerized medical records of women who attended a large maternity hospital between 2009 and 2017 for their first and second singleton deliveries were analyzed. Women who had their weight first measured after 15 weeks of gestation in either pregnancy were excluded.Results: Of the 9,724 women, the incidence of obesity increased from 11.6% in the first pregnancy to 16.0% in the second. The mean interpregnancy interval was 32.5 ± 15.7 months, and median BMI change was +0.6 kg/m2 (interquartile range 2.2; P < 0.001). Overall, 10.3% (1,006/9,724) developed overweight and 5.9% (571/9,724) developed obesity by the second pregnancy. Of the nulliparas in the overweight category, 20.6% (526/2,558) entered the obesity category. The development of obesity by the second pregnancy was independently associated with a longer interpregnancy interval, formula feeding at hospital discharge, taking antidepressants or anxiolytics, and postnatal depression. Professional/managerial employment was associated with a lower odds ratio of developing obesity.Conclusions: Maternal obesity increased between the first and second pregnancy, with one-fifth of nulliparas in the overweight category developing obesity. Pregnancy-related factors were identified as predictors of developing obesity. Further research is needed to assess whether interventions targeting these related factors could optimize maternal weight management between pregnancies. [ABSTRACT FROM AUTHOR]

Aim: Increased maternal body mass index (BMI) has been consistently associated with elevated blood glucose levels during pregnancy. Studies to date investigating the relationship between maternal blood glucose levels and dietary intake have shown mixed results. We investigated the association between maternal fasting plasma glucose (FPG) levels and food group and macronutrient intakes in the first trimester of pregnancy, after adjustment for maternal bodyweight. Methods: Women were recruited after sonographic confirmation of an ongoing singleton pregnancy in the first trimester. Dietary information was collected using the validated Willett Food Frequency Questionnaire. Maternal height and weight were measured and BMI calculated. Body composition was measured using advanced bioelectrical impedance analysis. FPG levels were obtained for women who were selectively screened with a 75 g oral glucose tolerance test. Results: No associations were observed between maternal FPG levels and food group or macronutrient intakes but higher energy and starch intakes were found in obese subjects (P = 0.009 and P = 0.03 respectively). On univariate analysis, higher FPG levels were associated positively with higher maternal bodyweight, BMI, body fat, fat free mass and visceral fat (all P < 0.001). However, on multivariate regression analysis, higher FPG levels remained associated only with maternal BMI > 29.9 kg/m2 (OR 7.4, P = 0.01). Conclusions: Our findings indicate that maternal BMI is the key determinant of maternal glycaemia. Interventions which focus on overall energy restriction and especially the limitation of dietary starch to optimise prepregnancy maternal bodyweight are likely to be useful in improving glycaemic control in higher risk pregnancies.

Introduction Maternal obesity has been identified as an important clinical priority in contemporary obstetrics. This study aimed to determine the incidence of maternal obesity in early pregnancy and track recent trends in body mass index ( BMI) categories over 5 years 2009-2013. Material and methods This prospective observational study included all women who delivered an infant weighing ≥500 g during the 5 years 2009-2013 in a large university teaching hospital in Ireland. Body mass index was calculated using early pregnancy weight and height measured at first antenatal visits. Sociodemographic and clinical data were gathered prospectively. Trends in maternal obesity were tracked over 5 years and epidemiological associations with obesity were examined using logistic regression, adjusted for confounding variables. Results Of 42 362 women, 99.0% ( n = 41 927) were eligible for analysis with a mean BMI of 25.5 kg/m2, mean age of 30.7 years and 40.7% ( n = 17054) primigravidas. The absolute number of cases of severe obesity ( BMI ≥40.0 kg/m2) increased by 48.5% from 2009 to 2013 ( p < 0.001). After multivariate logistic regression analyses, obesity incidence increased with increasing parity, advancing age and socioeconomic disadvantage. The maternal obesity rate among women born in the 13 European Union Accession countries was 8.6%, nearly half that of those born in existing European Union countries ( p < 0.001). Conclusion It is concerning that while the overall obesity rate remained stable, the number of cases of severe obesity increased over 5 years. We recommend renewed public health efforts addressing obesity rates before pregnancy and reinforcing attempts to optimize a woman's weight after delivery. [ABSTRACT FROM AUTHOR]
