Construction of a short form of the healthy eating behaviour inventory for the Japanese population.

INTRODUCTION The present study constructed a short form of the Healthy Eating Behavior Inventory suitable for use in the Japanese culture (HEBI-J) and confirmed the scales preliminary reliability and validity. METHODS In Study 1, Japanese adults (N=75) completed a free-response questionnaire about healthy eating behaviours. Thematic analysis was used to identify three factors-balance, pattern, and restriction-associated with healthy eating behaviours and 12 items related to these healthy eating behaviours. In Study 2, Japanese office workers (N=784) completed two questionnaires regarding 12 items of healthy eating behaviours and the dietary stages of change. RESULTS Confirmatory factor analysis demonstrated that the three-factor model was appropriate (GFI=.94, AGFI=.90, CFI=.90, RMSEA=.08, SRMR=.53). Reliability was confirmed by alpha coefficients and the Spearman-Brown formula. Concurrent validity was confirmed by the relationship between the healthy eating stages. CONCLUSIONS This study demonstrated the preliminary reliability and validity of the HEBI-J.

Exploring physical activity with a low psychological burden and high feasibility in Japan: a qualitative study.

Abstract Previous research has shown that physical activity with a low psychological burden and high feasibility (i.e. a focus on small lifestyle changes) contributes to the adoption of and long-term success in behavior change intervention. The present study aims to explore the physical activity with a low psychological burden and high feasibility in which people already engage in their everyday life in Japan. Sixty-four participants (22 males and 42 females ranging in age from 36 to 89) participated in a qualitative research survey that asked what type of physical activity they engaged in on a daily basis to maintain good health. Results of a thematic analysis revealed nine themes (behavioral categories), which included four core themes of exercise, gymnastic exercises, stretch exercises, sports, and strength training, and five core themes of nonexercise activity, walking, cleaning, using the stairs, engaging in agriculture, and gardening based on a description analysis. A thematic map was constructed based on Japanese physical activity guidelines. Key findings of this study are as follows: (1) walking has a low psychological burden and high feasibility; (2) gymnastic exercise is efficacious from a physical and psychological perspective; (3) nonexercise activities are more acceptable than exercise activities; and (4) a focus on intervention with nonexercise activities has the potential for high engagement in the Japanese population. The study indicates that significant resources are available for promoting health behavior change interventions that would increase physical activity in the Japanese population.

Evaluation of Intervention Reach on a Citywide Health Behavior Change Campaign Cross-Sectional Study Results

Little is known about dissemination strategies that contribute to health information recognition. This study examined (a) health campaign exposure and awareness (slogan and logo recognition); (b) perceived communication channels; (c) differences between perceptions of researcher-developed and enhancement community health information materials; and (d) differences in campaign awareness and communication channels, according to Japanese community demographic characteristics. A cross-sectional survey (N = 508) was conducted in Tokigawa, Japan, in 2013. The Small Change Campaign focused on increasing physical activity and improving dietary habits. Information dissemination was carried out using leaflets, newsletters, posters, website, local public relations magazines, health classes, events, and online newsletters. The participants completed a survey assessing their campaign awareness (i.e., slogan and logo) and exposure to the informational materials presented during the campaign. Fewer than half (45.4%) knew the slogan, and only 24.4% were aware of the logo. Public relations magazines, leaflets, and newsletters were significantly better-perceived health communication channels. Researcher-developed and enhancement community health information materials were equally recognized (p = .34, w = .08). Furthermore, women and those who were employed were significantly more aware of the slogan, logo, and communication materials. Further research should explore effective communication strategies for community-based health promotion intervention via randomized control trials.
