Although impulsivity has been implicated in the development and maintenance of obesity, evidence linking impulsivity to obesity has been mixed. These mixed findings may be related to differences in the type of impulsivity measures used and the varied domains of impulsivity assessed by each measure. The present meta-analysis aimed to examine the impact of measurement selection on the relationship between impulsivity and body mass index (BMI). A total of 142 articles met inclusion criteria and were comprised of 315,818 participants. Effect sizes consisted of Fisher's z-transformed correlation coefficients, which were weighted by the inverse variance to establish the grand mean estimate of the relationship between impulsivity and BMI. Overall weighted mean effect sizes also were computed for each type and domain of impulsivity measure. Moderator analyses were conducted using a mixed-effects approach to determine if the relationship between impulsivity and BMI varied between the types of impulsivity measures used. On average, participants were 32.25 (SD = 12.41) years of age, with a BMI of 26.63 (SD = 5.73) kg/m2. The overall relationship between impulsivity and BMI was small but significant (r = .07). Behavioral task measures of impulsivity produced significantly larger effect sizes (r = .10) than did questionnaire measures of impulsivity (r = .05). Domains of impulsivity that assessed disinhibited behaviors (r = .10), attentional deficits (r = .11), impulsive decision-making (r = .10), and cognitive inflexibility (r = .17) produced significant effect sizes. These meta-analytic findings demonstrate that impulsivity is positively associated with BMI and further document that this association varies by the type of impulsivity measure used and the domain of impulsivity assessed.

Objective The present study aimed to describe the experience of, and factors associated with, disordered eating in a population‐based sample of emerging adults during the COVID‐19 outbreak. Method Participants in the EAT 2010–2018 (Eating and Activity over Time) study were invited to complete the C‐EAT (COVID‐19 EAT) survey in April–May 2020. There were 720 respondents to the survey (age: 24.7 ± 2.0 years). Psychological distress, stress, stress management, financial difficulties, and food insecurity during the COVID‐19 pandemic were examined as cross‐sectional correlates of disordered eating in 2020. Open‐ended questions assessed the perceived impact of the pandemic on eating behaviors. Results Low stress management was significantly associated with a higher count of extreme unhealthy weight control behaviors (UWCBs). Food insecurity, higher depressive symptoms, and financial difficulties were significantly associated with a higher count of less extreme UWCBs. Higher stress and depressive symptoms were significantly associated with greater odds of binge eating. Six themes pertaining to disordered eating during the pandemic emerged: (a) mindless eating and snacking; (b) increased food consumption; (c) generalized decrease in appetite or dietary intake; (d) eating to cope; (e) pandemic‐related reductions in dietary intake; and (f) re‐emergence or marked increase in eating disorder symptoms. Discussion Psychological distress, stress management, financial difficulties, and abrupt schedule changes may have contributed to disordered eating during the COVID‐19 pandemic. Interventions that target stress management, depressive symptoms, and financial strain and provide tools to develop a routine may be particularly effective for emerging adults at risk of developing disordered eating during public health crises.
IMPORTANCE Most women who quit smoking during pregnancy will relapse postpartum. Previous efforts to prevent postpartum relapse have been unsuccessful at increasing rates of sustained abstinence. OBJECTIVE To evaluate the relative efficacy of 2 different approaches to prevent postpartum smoking relapse. DESIGN, SETTING, AND PARTICIPANTS Pregnant women who recently had quit smoking were recruited before the end of pregnancy. Intervention sessions were conducted through a combination of telephone calls and in-person visits beginning at delivery and continuing through 24 weeks postpartum. Participants completed assessments at the prenatal baseline and at 12, 24, and 52 weeks postpartum. Participants were recruited between March 2008 and December 2012. The dates of the analysis were April 2014 to February 2015. INTERVENTIONS Women received postpartum-adapted, behavioral smoking relapse prevention intervention and were randomly assigned to an enhanced cognitive behavioral intervention that included additional specialized strategies and content focused on women's postpartum concerns about mood, stress, and weight (Strategies to Avoid Returning to Smoking [STARTS]) or a supportive, time and attention-controlled comparison (SUPPORT). Intervention began before delivery and continued through 24 weeks postpartum. MAIN OUTCOMES AND MEASURES The primary outcome was biochemically confirmed sustained tobacco abstinence at 52 weeks postpartum. Secondary outcomes were self-reported mood, levels of perceived stress, and degree of concern about smoking-related weight gain. RESULTS The study cohort comprised 300 participants (150 randomly assigned to each group). Their mean (SD) age was 24.99 (5.65) years. Overall, 38.0% (114 of 300), 33.7% (101 of 300), and 24.0% (72 of 300) of the sample maintained abstinence at 12, 24, and 52 weeks' postpartum, respectively. There were no differences between the intervention groups in abstinence or time to relapse. Self-reported depressive symptoms and perceived stress significantly improved over time, and improvements were similar for both intervention groups. Women with more depressive symptoms and higher levels of perceived stress were more likely to relapse (hazard ratio, 1.
Objective This study examined the prevalence of and changes in loss of control over eating (LOC) among pregnant women with overweight/obesity, along with associations between LOC and depressive symptoms and stress. Method Community women (N=200; BMI≥25; 12–20 weeks gestation) reported LOC before and during early pregnancy using the Eating Disorder Examination, which was adapted for administration in pregnancy. Women self-reported depressive symptoms and stress during early pregnancy. Results Twenty-eight percent (n=56) of women reported LOC before or during early pregnancy: 14.5% (n=29) reported LOC incidence during early pregnancy, 9.5% (n=19) reported LOC persistence from pre-pregnancy to early pregnancy, and 4.0% (n=8) reported LOC pre-pregnancy only. Women with LOC reported more depressive symptoms and stress than did those without. Women with LOC persistence reported clinically-significant depressive symptoms and elevated stress. Levels of depressive symptoms and stress differed between women with LOC persistence and those without LOC (ps<.05). Discussion LOC during pregnancy was prevalent and associated with distress, particularly when present before and during pregnancy. Among women with LOC, few reported remission, but one-half reported onset during early pregnancy. Longitudinal studies are needed among mothers with overweight/obesity to identify patterns of LOC throughout pregnancy and how LOC affects perinatal outcomes.
