Although eating independence is important for older adults who require long-term care, the overall relationship between eating independence and oral condition, nursing care level, and rating of dementia remains unclear. This cross-sectional study investigated the relationship between eating independence and nursing care level, independence level due to dementia (rating of dementia), occlusal status, and dysphagia diet code among 238 residents of three long-term care facility in Koriyama, Fukushima Prefecture, Japan. Age, sex, nursing care levels, rating of dementia, eating independence, number of teeth, molar occlusion, and dysphagia diet code were assessed. Eating independence was categorized into three groups: independence, partial assistance, and total assistance. Multiple regression analysis showed that nursing care level (standardization coefficient (β) = 0.243, p < 0.001, 95% confidence interval (CI): 0.128–0.366), rating of dementia (β = 0.159, p = 0.006, 95% CI: 0.025–0.144), and dysphagia diet code (β = -0.345, p < 0.001, 95% CI: -0.371–-0.186) were significantly associated with eating independence among long-term care facility residents. Additional longitudinal studies are needed to elucidate these relationships.

Background: The study aimed to identify the lifestyle factors associated with weight gain among working-age people in Yugawara, Japan.

Methods: A cross-sectional study was conducted among the citizens aged 19–64 years in Yugawara town. Data were obtained between February and March 2015 using a household survey. A bi-variate logistic regression model was used to assess the components associated with overweight status. The level of statistical significance was set at p < 0.05.

Results: There were 717 participants. A body mass index (BMI) ≥18.5 and <25.0 was considered normal weight, and BMI ≥25.0 was considered obese. There were 137 (17.2%) participants with overweight and 580 (72.9%) with either normal weight. Overweight status was positively correlated with ‘being unable to manage stress’ (odds ratio [OR]: 1.66; 95% CI: 1.10, 2.51; p = 0.015), ‘stress relief by eating’ (OR: 1.63; 95% CI: 1.03, 2.57; p = 0.036), ‘stress relief by watching TV’ (OR: 1.70; 95% CI: 1.09, 2.66; p = 0.020), ‘feeling unhealthy’ (OR: 1.95; 95% CI: 1.16, 3.25; p = 0.011), ‘eating dinner alone’ (OR: 1.58; 95% CI: 1.03, 2.44; p = 0.038) and ‘lower frequency of drinking alcohol’ (OR: 2.16; 95% CI: 1.41, 3.32; p < 0.001).

Conclusion: This study found that in working-age Japanese people, weight gain is influenced by stress factors, highlighting the significance of a good stress management approach to avert obesity and related health problems.

Although space travel is no longer a dream, galactic cosmic rays (GCR) including Heavy Ion Beam (HIB) is considerable risk factors for cancer development. Number of G1 and G2 C57BL/6J backcross mice from recovered C57BL/6J G0 male mice with ¹²C, ¹⁴N, ²⁰Ne, ⁴⁰Ar or ⁵⁶Fe-Ion Beams (HIBs) exposure was reduced especially in the high-energy condition. G1 mice from exposed dominant tumor resistant mice with 5 Gy of ²⁰Ne exposure slightly augmented skin papilloma development risk after the two stage chemical skin carcinogenesis procedure. Single dose high energy HIB exposure is a risk factor of cancer development and male fertility, considered protectable.
