Background: This study aimed to determine the relationship between food security and dietary habits and subjective health and subjective well-being among residents of a large-scale housing complex in Japan. Methods: This study used a cross-sectional design through a self-administered questionnaire survey. The study subjects were residents of Mukogawa Danchi in Nishinomiya City, Hyogo Prefecture, Japan, and data from 515 households out of 6,857 total dwelling units were used for the analysis. Food security status (HFSSM), dietary diversity score (HDDS), diet, eating behavior, subjective sense of health, and subjective sense of well-being were examined using logistic regression analysis. Results: Food insecurity was negatively associated with household dietary diversity scores (OR [95%CI]:0.49 [0.24–0.98] p = 0.044). Similarly, food insecurity was negatively associated with having a nutritionally balanced diet and having a satisfactory amount of food. There was also a negative association with family meals. There was a negative association between food insecurity and a subjective sense of health and a negative association (0.35 [0.15–0.78] p = 0.011) with a subjective sense of well-being among those aged 65 and older. Conclusions: In a large-scale housing complex in Japan, inadequate dietary intake was observed in food-insecure households; they ate meals less frequently with their families. Additionally, residents experiencing food insecurity tended to have lower subjective health and subjective well-being, depending on their age.

This study investigated the relationship between postpartum neck-upper extremity pain and specific childcare, housework, and daily activities. A survey of 312 Japanese women who gave birth in the past three years yielded 261 valid responses (mean age 32.2 ± 4.4 years). Pain intensity was measured using the Numerical Rating Scale (NRS), and pain location was identified through a multiple-choice body schema. Activities contributing to pain were identified from a predefined list, including childcare, housework, and daily living. Descriptive statistics and linear regression analyses explored these relationships. Results showed that 224 women (85.8%) reported neck-upper extremity pain, with a mean NRS score of 5.5 ± 2.2. Significant associations were found between specific activities and pain locations: baby carrier use with ulnar wrist pain; breastfeeding, washing the baby’s head, changing clothes, diapering, carrying heavy shopping bags, dishwashing, hanging clothes, and using a whipper with radial wrist pain; changing clothes with thumb carpometacarpal joint pain; feeding with a baby bottle and bathing with thumb metacarpophalangeal joint pain; carrying and picking up the baby from the floor and smartphone use with neck pain; smartphone use with shoulder pain; and using a baby stroller and changing the baby’s clothes with lateral elbow pain. In summary, many women experience moderate neck-upper extremity pain postpartum, related to specific childcare, housework, and daily activities. This study confirms that certain postpartum neck-upper extremity pains are associated with particular movements and activities.
