The weight of fatherhood: Identifying mechanisms to explain paternal perinatal weight gain

Saxbe, Darby, Corner, Geoffrey W., Khaled, Mona, Horton, Katelyn, Wu, Brian, Khoddam, Hannah Lyden·2018·Health Psychology Review

Abstract

Men appear to gain weight during the transition to parenthood, and fathers are heavier than non-fathers. Paternal perinatal weight gain may set weight trajectories in midlife and have long-term health implications. Since men do not undergo the physical demands of pregnancy and breastfeeding, the specific mechanisms underlying weight gain in new fathers warrant investigation. This review aims to stimulate research on paternal perinatal weight gain by suggesting testable potential mechanisms that (1) show change across the transition to parenthood and (2) play a role in weight and body composition. We identify seven mechanisms, within three categories: behavioural mechanisms (sleep, physical activity, and diet), hormonal mechanisms (testosterone and cortisol), and psychological mechanisms (depression and stress). We also discuss direct effects of partner pregnancy influences (e.g., 'couvade syndrome') on men's body weight. In presenting each mechanism, we discuss how it may be affected by the transition to parenthood, and then review its role in body composition and weight. Next, we describe bidirectional and interactive effects, discuss timing, and present three broad research questions to propel theoretical development.

  • In fathers, hormonal imbalances may be related to postpartum depression, but lack of sufficient sleep may also play a role.

    “As in mothers, in fathers, hormonal imbalances may be related to postpartum depression (Saxbe et al., 2018), but lack of sufficient sleep may also play a role: 35% of parents with children under age 2 report that they get only 5–6 hr of sleep per night (Krueger & Friedman, 2009).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
