Sleep Characteristics and Prevalence of Perceived Insufficient Sleep Across Age Groups in the Japanese Community-Based General Population
This study aimed to provide basic data according to age on objective sleep duration distribution and sleep characteristics via subjectivity, and to determine the prevalence of insufficient sleep and related sleep parameters in the general Japanese population. Data from the second survey of the Japan Multi-Institutional Cohort (J-MICC) Daiko Study were used for the analysis, with 2091 participants (1556 women; 58.6 ± 9.8 years old) included. Quest…
The Inverse Association between the Frequency of Forest Walking (Shinrin-yoku) and the Prevalence of Insomnia Symptoms in the General Japanese Population
Since a single forest walk (Shinrin-yoku or forest bathing) session is reported to improve sleep temporarily, occasional forest walks may have a positive effect on daily sleep. Therefore, this study aimed to examine whether more frequent forest walking is associated with better daily sleep conditions. Data from the second survey of the Japan Multi-Institutional Collaborative Cohort (J-MICC) Daiko Study conducted among residents of Nagoya City, Ja…
Food group intakes and high-sensitivity C-reactive protein among community-dwelling Japanese adults
Objective: Healthy dietary patterns have been linked to lower levels of chronic inflammation. The present study aimed to investigate the associations between food group intakes and high-sensitivity C-reactive protein (hsCRP) among community-dwelling adults. Design: Cross-sectional. Setting: Three areas in Japan (Shiga, Fukuoka, or Kyushu and Okinawa). Participants: The present analysis included 13 648 participants (5126 males and 8522 females; ag…
Association between consumption of small fish and all-cause mortality among Japanese
Objective: Although small fish are an important source of micronutrients, the relationship between their intake and mortality remains unclear. This study aimed to clarify the association between intake of small fish and all-cause and cause-specific mortality. Design: We used the data from a cohort study in Japan. The frequency of the intake of small fish was assessed using a validated FFQ. The hazard ratio (HR) and 95 % confidence interval (CI) f…
Anti-Helicobacter pylori antibody status is associated with cancer mortality
Paradoxically, patients with advanced stomach cancer who are Helicobacter pylori -positive (HP + ) have a higher survival rate than those who are HP - . This finding suggests that HP infection has beneficial effects for cancer treatment. The present study examines whether HP + individuals have a lower likelihood of death from cancer than those who are HP - . Prospective cohort data ( n = 4,982 subjects enrolled in the DAIKO study between 2008–201…
The association between self-rated health and high-sensitivity C-reactive protein level
The present study demonstrated that poor SRH is cross-sectionally associated with higher serum hsCRP level. However, the longitudinal data did not support the relationship between serum hsCRP level at baseline and future SRH. Further longitudinal studies that include data on mortality and multiple inflammatory markers are warranted to elucidate the possible role of low-grade inflammation in the association between SRH and mortality risk
Impact of alcohol intake on total mortality and mortality from major causes in Japan
OBJECTIVES: Using common alcohol consumption categories, to conduct a pooled analysis of six ongoing large-scale cohort studies in Japan in order to produce concrete estimates of the quantitative contribution of alcohol consumption to all-cause and major causes of mortality in the Japanese population. METHODS: Of the 309 082 subjects, there were 35 801 deaths during 3 832 285 person-years of follow-up. Using a random-effect model, we conducted a …
Perceived Psychologic Stress and Colorectal Cancer Mortality
OBJECTIVE: The purpose of this research was to examine the relationship between perceived psychologic stress and colorectal cancer mortality in a prospective large-scale study. METHODS: Between the years 1988 and 1990, 32,153 men and 45,854 women aged 40 to 79 years were enrolled. Participants completed a self-administered questionnaire that addressed demographic, lifestyle, and psychosocial characteristics. Subjects were subsequently followed fo…

OBJECTIVES: Using common alcohol consumption categories, to conduct a pooled analysis of six ongoing large-scale cohort studies in Japan in order to produce concrete estimates of the quantitative contribution of alcohol consumption to all-cause and major causes of mortality in the Japanese population. METHODS: Of the 309 082 subjects, there were 35 801 deaths during 3 832 285 person-years of follow-up. Using a random-effect model, we conducted a …
