Hunger, temptation, and dietary adherence during weight management

Preliminary evidence suggests that hunger and temptation may predict nonadherence to dietary intake goals; however, no studies have investigated the potential interaction between hunger and temptation in relation to dietary nonadherence nor have any investigated whether these associations may be different after the end of active behavioral intervention. Thus, the current study examined the week-to-week associations between hunger, temptation, and dietary adherence in 74 adults with overweight or obesity (mean ± SD age = 50.7 ± 10.4, BMI = 31.2 ± 4.5 kg/m2) enrolled in a 12-week, Internet-based weight loss program followed by a 40-week post-intervention observational maintenance period. Each week during the study, participants completed a questionnaire on which they rated their hunger, temptation, and dietary adherence on 7-point scales. Multilevel models demonstrated that higher levels of hunger and temptation were associated with lower ratings of dietary adherence during the same week, ps < 0.0001, such that 1-point higher ratings of hunger or temptation were associated with 0.2- and 0.5-point lower ratings of dietary adherence, respectively. Further, there was an interaction between hunger and temptation such that the association between temptation and dietary nonadherence was stronger when ratings of hunger were lower, p = .028. There were no differences in associations between the initial weight loss period and the maintenance period. Results suggest that hunger and temptation may serve as potential treatment targets for interventions aimed at improving adherence to dietary intake goals. Future studies should investigate whether interventions targeting hunger and temptation can improve dietary adherence and weight loss outcomes.

Text Messaging to Enhance Mindfulness-Based Smoking Cessation Treatment: Program Development Through Qualitative Research

Background

Mindfulness-based programs show promise for promoting smoking cessation in diverse populations. Mobile health strategies could increase treatment engagement and in-the-moment support, thus enhancing the effects of mindfulness-based smoking cessation interventions. However, most mobile health programs have been developed without sufficient input from the target population.

Objective

By eliciting input from the target population, predominantly low socioeconomic status (SES) African American adult smokers, throughout the development of an SMS (short message service) text messaging program that teaches mindfulness for smoking cessation, we aimed for the resulting program to be optimally effective and consistent with participants’ needs and preferences.

Methods

Two qualitative studies (N=25) were conducted with predominantly low SES, African American adult smokers. In Study 1 (initial qualitative input; n=15), participants engaged in focus groups to provide suggestions for program development. In Study 2 (abbreviated trial; n=10), participants received a 1-week version of the SMS text messaging program and provided feedback through in-depth interviews.

Results

In Study 1, participants suggested that the SMS text messaging program should be personalized and interactive (ie, involve two-way messaging); provide strategies for coping with cravings and recovering from smoking lapses; involve relatively short, to-the-point messages; and include pictures. In Study 2, participants were highly engaged with the texts, indicated that the program was useful, and provided additional suggestions for improvement.

Conclusions

Eliciting feedback from the target population throughout the intervention development process allowed for iterative revisions to increase feasibility, acceptability, and effectiveness. Overall, SMS text messaging appears to be a feasible, appealing way to provide in-the-moment personalized support and encourage mindfulness among low-income African American smokers.
