Feeding Under Fire: Relations between parental stress hormones and controlling feeding behaviors

Appetite. 2024 Apr 17:107365. doi: 10.1016/j.appet.2024.107365. Online ahead of print.ABSTRACTUnder stress, parents tend to use more controlling feeding behaviors toward their children (Berge et al., 2017; Doan et al., 2022; Loth et al., 2016). However, the majority of prior work focuses on subjective reports of stress, and there is a dearth of research examining parental physiological stress and its impact on feeding behaviors. In the current study, we examined how parental physiological stress reactivity would influence their feeding behaviors under mild stress in a lab-based setting. Parents (n = 83, 50 % females) and their children (59% female, Mage =42 months, SD=4.48) participated. Stress was induced using the Trier Social Stress Test in the laboratory (Kirshbaum et al., 1993). Salivary samples were collected at 4 time points during the visit to index stress reactivity and later assayed for cortisol and DHEA. Parent-child interactions during the anticipatory period of the stress test were observationally coded for parent use of controlling feeding behaviors. To examine whether parent stress physiology predicts their feeding behaviors, we ran a Poisson regression using income, parent ethnicity, parent sex (mom/dad), time of day, and DHEA/cortisol ratio as predictors of controlling feeding behavior. Latinx parents used less controlling feeding behaviors, b = -.323, p = .041 than non-Latinx parents. Parents with a higher DHEA/Cortisol ratio were less likely to use controll...
