An exploratory analysis of the impact of a university campus smoking ban on staff and student smoking habits in Japan.

Background: Smoking bans in public places have been shown to have an impact on smoking habits, however the potential influence of a university smoking ban on faculty and staff smoking habits remains elusive.

Methods: This cross sectional study was implemented in Nayoro City, Japan in 2011, among the faculty and students of the Nayoro City University. Five years after the declaration of a total ban on smoking on a university campus, the smoking characteristics of all students, teachers and office workers, and the policy's impact on smokers were investigated.

Early infantile growth and cardiovascular risks in adolescent Japanese women.

Objective: Early life events connected with the risk of later disease can occur not only in utero, but also in infancy. In study of the developmental origins of health and disease, the relationship between infantile growth patterns and adolescent body mass index and blood pressure is one of the most important issues to verify.

Materials And Methods: We analyzed the correlation of current body mass index and systolic blood pressure of 168 female college students with their growth patterns in utero and in infancy.

Three-year follow-up on the effects of a smoking prevention program for elementary school children with a quasi-experimental design in Japan.

Objective: We performed the follow-up tests for three years for junior high school students by the quasi-experimental design to investigate the medium-term effect of smoking prevention education in the elementary school.

Methods: The intervention group consisted of 106 school students of three elementary schools and received a smoking prevention program in the elementary school. Moreover, the follow-up tests were conducted at each grade of junior high school, and the booster program was mailed.

Post-traumatic stress disorder in pre-school aged children after a gas explosion.

Unlabelled: To evaluate the sensitivity of diagnostic criteria for post-traumatic stress disorder (PTSD) in pre-school aged children involved in a gas explosion, post-traumatic symptoms of the children were investigated four times after the accident, immediately, 10 days, 6 months, and 1 year later. Using symptoms at 6 months after the accident, sensitivity of diagnostic criteria was assessed by comparing the fourth edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), and the alternative criteria for infants and young children [10]. In addition, the published Child Post-Traumatic Stress Disorder Reaction Index (CPTSD-RI) and its modified version proposed by us were also evaluated their sensitivity to rate the symptoms.

Fetal growth and the timing of exposure to maternal smoking.

Background: Maternal smoking during the third trimester reduces the birthweight of the full-term neonate. We assessed the relationship between the timing of exposure to maternal smoking, gestational period, weight and body length for both full-term and preterm neonates.

Methods: A retrospective study with a questionnaire was conducted in 1194 infants who participated in the official medical examination for 3-year-old infants.
