Beliefs about weight gain among young adults: potential challenges to prevention.

This study assessed young adults' beliefs about weight gain with the goal of improving intervention efforts with this high-risk group. A total of 1,347 incoming freshman (45% male; 81% non-Hispanic white; 18.6 ± 1.7 years; BMI = 23.3 ± 2.3 kg/m2) at a large state university in the Northeast completed a survey designed to assess: (i) degree of concern about weight gain, (ii) level of interest in weight control programs, and (iii) the most acceptable setting for an intervention. Perceptions about freshman weight gain were consistent across gender, with men and women reporting that the average student gains 5.4 ± 1.9 kg and 5.6 ± 1.9 kg respectively. Men in general were less concerned about weight gain (P < 0.001) and reported they would have to gain 6.2 ± 4.2 kg before becoming concerned compared to 3.1 ± 1.7 kg among women (P < 0.001). Overweight (OW) men were more concerned about gaining weight than normal weight (NW) men (P < 0.001) and indicated they would have to gain less weight before becoming concerned (5.0 ± 3.0 kg vs. 6.7 ± 4.5 kg, P < 0.001). Fewer men reported they would join a program to prevent weight gain (17% men vs. 40% women, P < 0.001); the percentage of men willing to join a prevention program did not vary by weight status (P = 0.59). Both men and women were most likely to report a willingness to attend classes on a local college campus compared to other settings. Findings highlight the challenges of engaging young adults in weight gain prevention programs, particularly young men, and are discussed in terms of implications for improving recruitment efforts and intervention development with this population.
