Brief Summary

Understanding critical periods during which people are at risk to gain weight or display unhealthy changes in energy balance related behaviour, i.e. eating, physical activity and sedentary behaviour, can facilitate the development of weight gain prevention programs. Although the transition to parenthood is associated with pregnancy-related weight gain and retention in women, evidence on the effect of having a first child on men's body weight is lacking. It is also unclear whether pregnancy-related weight gain and retention cohere with unfavourable changes in body composition and energy balance related behaviour in both women and men transitioning to parenthood. Using a mixed-methods design, the investigators aim to provide insight into this critical life phase. An observational follow-up study will be used to investigate changes in body weight, body composition and energy balance related behaviour among couples from pre-conception to one year postpartum, and to identify those most at risk for excessive weight gain.

Study Arms (1)

Data collection

Data will be collected at four time points over the course of approximately one year and nine months. Participating couples (women and men) will be recruited during the first trimester of their first pregnancy. First measurement will take place in the week of the first routine ultrasound scan (week 12 of pregnancy) (=T0). First follow-up measures will take place six weeks postpartum (=T1). The second and third follow-up measurements will take place at six months postpartum (=T2) and twelve months postpartum (=T3).

Other: Measurements of body composition

Interventions

Body weight (SECA digital weighing scale), height (SECA stadiometer), body composition (TANITA Bioelectrical Impedance Analyzer \& skin fold thickness measurements at the biceps, triceps, subscapular and suprailiac sites) and waist circumference (Cescorf measuring tape) will be objectively measured.

  • Women having a multiple pregnancy (twin, triplet,…).
