Changes in the sleeping habits of Japanese university students during the COVID-19 pandemic: a 3-year follow-up study.

Background: The coronavirus disease 2019 (COVID-19) pandemic has greatly changed our daily life. Owing to the imposed restrictions, many educational facilities have introduced remote teaching. This study aims to clarify the association between remote teaching and Japanese university students' sleeping habits.

Smoking cessation after cancer diagnosis reduces the risk of severe cancer pain: A longitudinal cohort study.

Background: Whether abstinence from smoking among cancer patients reduces cancer pain is still unclear. Opioids can act as a surrogate index for evaluating the incidence of severe cancer pain in countries where opioid abuse is infrequent. This study aimed to investigate whether changed smoking behavior after cancer diagnosis influences the incidence of severe cancer pain as determined by strong opioid use.

The impact of the National Health Program on diabetes incidence among working-age men with prediabetes: A regression discontinuity analysis of a nation-wide database in Japan.

Aim: This study aimed to investigate the impact of the National Health Program in Japan ("Specific Health Check-ups and Specific Health Guidance") on diabetes prevention among working-age men with prediabetes.

Methods: This study used a regression discontinuity design, based on the program's criterion that the program starts at age 40 or older and that the intervention is provided only to prediabetic individuals with abdominal obesity, to assess the impact of the program on the diabetes incidence in a total of 49,848 men with prediabetes, aged 37-42 years.

Results: The National Health Program in which interventions were provided for individuals aged 40 years or over with both prediabetes and abdominal obesity was associated with a decrease in diabetes incidence rate equivalent to 10.

Sex differences in the association between fatty liver and type 2 diabetes incidence in non-obese Japanese: A retrospective cohort study.

Aims/introduction: Asians develop type 2 diabetes at a lower body mass index (BMI) compared with other races, which is partly because of Asian-specific fat depots. Sex plays a role in fat deposition, regardless of race. This retrospective cohort study aimed to investigate the association among fatty liver, sex and type 2 diabetes in non-obese Japanese.

Design: Cross-sectional study.

Setting: Data were collected at two work sites of Japanese electronics manufacturing company in 2015.

Inverse association of des-acyl ghrelin with worksite blood pressure in overweight/obese male workers.

Background: Job strain, defined as a combination of high job demands and low job control, has been reported to elevate blood pressure (BP) during work. Meanwhile, a recent experimental study showed that ghrelin blunted the BP response to such mental stress. In the present study, we examined the hypothesis that des-acyl ghrelin may have some beneficial effects on worksite BP through modulating the BP response to work-related mental stress, i.
