The following study was designed to identify the aspects of orthorexia nervosa in Korea and the relationship between orthorexia nervosa and fear of obesity to establish the basis for diagnosis of orthorexia nervosa.

We collected Dusseldorf Orthorexia Scale (DOS), perceived suspectibility and severity to obesity, fear of obesity, Korean Overall Body Esteem Scale (K-OBES), body mass index (BMI), subjective evaluation of obesity degree, body satisfaction, reason for diet and demographic characteristics from 321 adults and then analyzed the data using SPSS 23.0.

The results showed that perceived severity to obesity and subjective evaluation of obesity degree was negatively correlated with DOS and had significant effect on DOS. These findings suggest orthorexia nervosa is not behavior to prevent and manage obesity. Also, the relationship between DOS and demographic characteristics such as gender and age and psychological variable such as fear of obesity, body esteem and satisfaction was not significant.

Orthorexia nervsoa is an independent condition that distinguishes it from anorexia nervosa, which shows a fear of obesity, a disturbance in the way to experience their body and difference between sex. Last, the limitations and implication for future work are discussed.

The purpose of this study was to examine whether food craving mediated effects on the relationship between stress and obesity in the elderly population.

A descriptive correlational study was conducted. The participants included 256 elderly who had been attending three geriatric welfare facilities in J city. Data were collected between 9^th and 20^th, July 2018 with a structured questionnaire and body measurement. The measurements included G-FCQ-T, SRI-MF, and BMI. The statistical analysis included t-test, Pearson correlation analysis, Cronbach’s α, and mediation analysis with bootstrapping as recommended by Hayes’ PROCESS macro (2016).

Mean BMI score was 23.95±3.79 kg/m² and the prevalence of obesity was 25.8%. Significant difference were observed in the age (χ²=19.54, p<.001), gender (χ²=13.80, p<.001), education (χ²=7.43, p=.024), number of diseases (χ²=12.69, p=.002), medication (χ²=18.82, p< .001), stress (t=−2.57 p=.011), and food craving (t=−2.63 p=.003). Stress and food craving (r=.50, p<.001), food craving and obesity (r=.23, p<.001), and obesity and stress (r=.28 p<.001) were found to be positively correlated with each other. Food craving was found to mediate the relationship between stress and obesity in the elderly population (B=0.38 (SE=0.19), 95% CI, [0.05, 0.79]).

We need therapeutic intervention with a focus on food craving for weight management in obese elderly people and the development of a nursing intervention to control elderly food craving.
