Neurocognitive Inhibitory Control Ability Performance and Correlations with Biochemical Markers in Obese Women.

ABSTRACT: Inhibitory control, the ability to suppress prepotent responses and resist irrelevant stimuli, is thought to play a critical role in the maintenance of obesity. However, electrophysiological performance related to different inhibitory control processes and their relationship with motor response inhibition and cognitive interference and potential biochemical mechanisms in middle-aged, obese women are as yet unclear. This work thus compared different neurocognitive Go/Nogo and Stroop task performance in healthy sedentary normal-weight and obese women, as well as their correlation with biochemical markers. Twenty-six healthy, sedentary obese women (obese group) and 26 age-matched (21-45 years old) normal-weight women (control group) were the participants, categorized by body mass index and percentage fat, as measured with dual-energy X-ray absorptiometry. They provided a fasting blood sample and performed two cognitive tasks (i.e., Go/Nogo and Stroop tasks) with concomitant electrophysiological recording. The N2 and P3 waveforms of event-related potential (ERP) were recorded. Although the between-group behavioral performance was comparable, the obese group relative to the control group showed significantly longer N2 latency and smaller P3 amplitude in the Stroop task and smaller N2 and P3 amplitudes in the Go/Nogo task. Significant inflammation response indices (e.g., CRP, leptin, adiponectin/leptin ratio) were observed in the obese group. The Nogo P3 amplitude was significantly correlated with the adiponectin/leptin ratio. These findings indicate that healthy obese women still exhibit deviant neurophysiological performance when performing Go/Nogo and Stroop tasks, where the adiponectin/leptin ratio could be one of the influencing factors for the deficit in neural processes of motor response inhibition.

Project description:INTRODUCTION:Maternal obesity and excessive gestational weight gain are related to adverse outcomes in women and children. Lifestyle interventions during pregnancy showed positive effects on decreasing weight gain during pregnancy, but effects on offspring's health and wellbeing are unclear. We aimed to assess the effect of lifestyle intervention programmes on offspring mental health, temperament, eating habits and anthropometric and cardiovascular measures. METHODS:Ninety-six offspring of pregnant women with a body mass index (BMI) ≥29 kg/m2 who were randomly assigned to 3 intervention groups during pregnancy (routine antenatal care, a brochure group or a prenatal session group) and 77 offspring of pregnant women with a normal BMI (between 18.5 and 24.9 kg/m2) were used as an additional control group in this analysis. When the children were between 3 and 7 years old, anthropometric and cardiovascular measurements were conducted and various questionnaires about offspring mental health, temperament and eating habits were filled out. RESULTS:Children of mothers who received a brochure-based lifestyle intervention programme showed significantly less surgency/extraversion compared to children of mothers who received routine antenatal care (contrast estimate = -0.36, SE = 0.15, p = 0.02, 95% CI [-6.66, -0.06]) and prenatal lifestyle intervention sessions (contrast estimate = -0.46, SE = 0.14, p < 0.01, 95% CI [-0.74, -0.18]) after adjusting for child's age, sex, offspring birth weight and mother's educational level. The lifestyle intervention could not be associated with any significant differences in offspring mental health, eating habits and anthropometric and cardiovascular characteristics. Children of mothers with a normal BMI showed less emotional problems (F(1, 156) = 5.42, p = 0.02) and internalizing (F(1, 156) = 3.04, p = 0.08) and externalizing problems (F(1, 156) = 6.10, p = 0.02) when compared to children of mothers in the obese group. DISCUSSION/CONCLUSION:The results suggest that a brochure-based lifestyle intervention programme can affect the offspring temperament. Future follow-up studies need to investigate how these temperament-related effects may influence obesity development later in life.
