This study examined the job satisfaction of nutritionists, and its effect on organizational commitment and turnover intention in public health centers. The response data of 174 nutritionists were analyzed. The overall average of job satisfaction was 3.94 out of 7 points, which was determined to be below ‘normal’; however, the job suitability of sub-factors scored 5.26, which was more than ‘normal’. The variables affecting job satisfaction that were provided by the respondents included job-related licenses (P＜0.01) and co-nutritionists (P＜0.01). Organizational commitment ranked ‘normal’ with a score of 4.35. Normative commitment (4.90) of the sub-factors was ‘normal’ or more, and differed when considering ‘age’ (P＜0.01), ‘employment status’ (P＜0.01), ‘salary per year’ (P＜0.05), and ‘working area’ (P＜0.05). The turnover intention was analyzed to be below ‘normal’ with 3.88 points, and the variables affecting turnover were significantly higher for subjects in their 20s (P＜0.01), less than two job-related licenses (P＜0.05), and less than two co-nutritionists (P＜0.01). The four variables of job satisfaction, ‘business discretion’ (P＜0.05), ‘work environment’ (P＜0.01), ‘job suitability’ (P＜0.01), and ‘reward’ (P＜0.01), positively affected the organizational commitment. Moreover, organizational commitment had a mediating effect (P＜0.01) on job satisfaction and turnover intention. Taken together, our results suggest that public health centers need to develop improvement plans for business discretion, work environment, job suitability and reward.
