Factors associated with self-reported health among New Zealand military veterans: a cross-sectional study

Narratives of holistic mental health recovery in New Zealand Defence Force personnel

Research on military mental health recovery has tended to focus on therapy outcomes while backgrounding the role of diverse healing influences. The New Zealand Defence Force (NZDF) is a bicultural military integrated with Māori customs and cultural perspectives on holistic health and wellbeing. This study used narrative analysis to examine the semi-structured interviews of 21 active duty NZDF personnel who had accessed mental healthcare to understand what factors contributed to their return to wellness. Narratives described an orientation toward recovery as a process, where many interrelated wellbeing and social factors together supported the return to health. Culturally available Māori wellbeing metaphors were adopted as heuristics by service members in their storying of growth and healing. Findings are considered in terms of how wellbeing and recovery are conceptualized and promoted within militaries with diverse cultures. Discussion focuses on how narratives within military institutions can promote resilience and support service member recovery from mental distress.

Association of the number of teeth and self-rated mastication with self-rated health in community-dwelling Japanese aged 40 years and older: the Yamagata cohort study

Self-rated health (SRH) is a predictive factor for health-related prognoses such as mortality. This study aimed to comprehensively investigate the risk factors for poor SRH in the general population of Japan, focusing on the combination of the number of teeth and self-rated mastication. Individuals aged at least 40 years in Yamagata Prefecture, Japan, were surveyed from 2017 to 2021. The participants answered a self-administered postal survey on lifestyle factors, medical history, physical and mental conditions, oral health, and dietary intake, and 6739 participants were included. Multivariate logistic regression analysis showed that individuals with less than 20 teeth and who bite tightly on one side or neither side were at a 1.422- and 1.952-fold significantly higher risk, respectively, of poor SRH than individuals with at least 20 teeth and who bite tightly on both sides. Moreover, individuals who had less than 20 teeth but could bite tightly on both sides did not have a significant risk compared to those who had at least 20 teeth and could bite tightly on both sides. Regarding individuals with more than 20 teeth, there was no difference between those who could and could not bite tightly on both sides, although the odds ratios for poor SRH tended to increase for those who could bite on one side or neither side. Our results emphasize the importance of having at least 20 teeth without periodontal disease and oral rehabilitation using a type of prosthesis for SRH, even with less than 20 teeth.
