    BACKGROUND: In Japan, specific health guidance is a program based on health checkups to prevent metabolic syndrome. However, dropout from the program is an issue and reduces opportunities to improve cardiovascular risk. Lack of awareness of health checkup results is thought to be associated with dropout, but the association remains unclear. This study aimed to investigate the impact of awareness of health checkup results with related attitude on dropout from specific health guidance among teachers. METHODS: Data from medical insurance providers primarily serving teachers (n = 7,031; mean age = 51.19 years old) were analysed. Participants were categorized into 3 groups based on awareness of health checkup results and attitude toward adopting healthy lifestyles at the first time of the health guidance: awareness with the attitude (level 1 group), awareness without the attitude (level 2 group), and lack of awareness (level 3 group). Dropout rates from specific health guidance and improvement in health checkup results in the following year were compared across groups. RESULTS: Dropout rates were 19.88% in the level 1 group, 22.03% in the level 2 group, and 27.77% in the level 3 group (P < 0.001 in a trend test). Compared with the level 1 group (reference), adjusted risk ratios for dropout were 1.139 (95% confidence interval: 1.001-1.295) for the level 2 group and 1.320 (95% confidence interval: 1.132-1.540) for the level 3 group. The degree of improvement in health checkup results decreased progressively from level 1 to level 3. CONCLUSIONS: Among the participants who received the first health guidance, awareness of health checkup results combined with attitude to adopt healthy lifestyles was associated with lower dropout from specific health guidance and greater improvements in cardiovascular risk. Such individuals' awareness and attitudes may help predict individuals at risk of dropout from health guidance in this population.

    School refusal behavior, defined as a child's prolonged voluntary absence from school for reasons unrelated to illness and/or economic hardship, is a growing concern in Japan. The COVID-19 pandemic has worsened this issue by disrupting children's lives. This review summarizes the prevalence, contributing factors, and health implications of school refusal, particularly in the context of COVID-19. A literature review of government reports and PubMed-indexed studies indicates that school refusal in Japan has been rising for eleven years, reaching a record 340,000 cases in 2023. Middle school students (6.7%) were the most affected, followed by elementary school students (2.1%). The pandemic intensified school-related, family-related, and child-related risk factors. School closures disrupted routines, reduced peer interactions, and increased social isolation, contributing to higher rates of anxiety and depression. Reports of suicides and mental health disorders among children have also surged. Family stressors, including economic hardship and parental mental health struggles, further exacerbate school refusal. Additionally, remote learning has widened socioeconomic disparities in access to education, leaving vulnerable children at greater risk. Addressing school refusal requires a multifaceted approach involving schools, families, healthcare providers, and policymakers. School-based interventions, mental health approach, and flexible educational programs would be essential. The Japanese government's "COCOLO Plan" represents progress toward a more inclusive education system, and a comprehensive, interdisciplinary strategy is needed. Ensuring all children receive the necessary support to reengage with education is critical to overcoming the long-term challenges posed by school refusal.

    超高齢社会の日本において,さらなる健康長寿を目指すためには,う蝕や歯周病のような歯科疾患を予防し健康な歯を多く残していくことが重要であり,口腔健康管理は疾病予防における重要領域の1つでもある。口腔健康管理は,関係機関や各種専門職が相互に連携しながら各々の立場で推進していくことが重要といえる。特に住民にとって身近な地域の薬局や薬剤師が口腔健康管理も含めた予防医療に果たす役割は非常に大きい。
