Background: Excessive gestational weight gain (GWG) is associated with short- and long-term health problems among mothers and their offspring. There is a strong need for effective intervention strategies targeting excessive GWG to prevent adverse outcomes.Methods: We performed a cluster-randomized controlled intervention trial in eight gynecological practices evaluating the feasibility and effectiveness of a lifestyle intervention presented to all pregnant women; 250 healthy, pregnant women were recruited for the study. The intervention program consisted of two individually delivered counseling sessions focusing on diet, physical activity, and weight monitoring. The primary outcome was the proportion of pregnant women exceeding weight gain recommendations of the Institute of Medicine (IOM). Secondary outcome variables were maternal weight retention and short-term obstetric and neonatal outcomes.Results: The intervention resulted in a lower proportion of women exceeding IOM guidelines among women in the intervention group (38%) compared with the control group (60%) (odds ratio (OR): 0.5; 95% confidence interval (CI): 0.3 to 0.9) without prompting an increase in the proportion of pregnancies with suboptimal weight gain (19% vs. 21%). Participants in the intervention group gained significantly less weight than those in the control group. Only 17% of the women in the intervention group showed substantial weight retention of more than 5 kg compared with 31% of those in the control group at month four postpartum (pp) (OR: 0.5; 95% CI: 0.2 to 0.9). There were no significant differences in obstetric and neonatal outcomes.Conclusions: Lifestyle counseling given to pregnant women reduced the proportion of pregnancies with excessive GWG without increasing suboptimal weight gain, and may exert favorable effects on pp weight retention.Trial registration: German Clinical Trials Register DRKS00003801. © 2013 Rauh et al.; licensee BioMed Central Ltd.

Context: The activation of peripheral immune cells and the infiltration of immune cells into adipose tissue in obesity are implicated in the development of type 2 diabetes mellitus. Objective: The aim of the study was to compare peripheral immune cells from obese and normal-weight women with regard to composition of immune cell subpopulations, surface expression of the chemokine receptors (CCRs) CCR2, CCR3, CCR5, and CXCR3 (chemokine (C-X-C motif) receptor 3) and cell-intrinsic migration capacity. Design: This was a case-control study. Setting: The study was conducted at a university clinical study center. Patients: Obese females and normal-weight females were included for fluorescence-activated cell sorting analysis and migration assays. Main Outcome Measures: Peripheral blood mononuclear cells were prepared from fasting blood samples and used for fluorescence-activated cell sorting analysis and migration assays. Results: An increase in the percentages of CD14+CD16 + monocytes was observed in obese subjects compared with controls. The CCR profile of monocytes differed significantly in the obese state; in particular, CCR2 levels were increased. In addition, a higher chemotactic activity of monocytes from obese subjects was observed in a migration assay, which was associated with both insulin resistance and CCR2 expression. Conclusion: Our results suggest that the enhanced intrinsic migratory capacity of peripheral monocytes in obese women may be due to the increased CCR expression, further supporting a link between peripheral immune cell dysfunction and obesity.
