“…Data were drawn from the prospective longitudinal Nicotine Dependence in Teens (NDIT) study conducted in Montréal, Canada [15]. A cohort of 1,294 students in grade 7, recruited in 1999 from 10 secondary schools, completed a self-report questionnaire at school every three months for a total of 20 surveys over the five years of secondary school (1999e2005).…”

A B S T R A C TPurpose: Heavy episodic (i.e., "binge") drinking (i.e., !five drinks/occasion) is highly prevalent among young adults; those who binge do so four times per month on average, consuming nine drinks on average on each occasion. Although it is well established that chronic heavy drinking (!two alcoholic beverages per day) increases the risk of hypertension, the relationship between binge drinking and blood pressure is not well described. Our aim was to describe the relationship between frequency of binge drinking, both current (at age 24 years) and past (at age 20 years), and systolic blood pressure (SBP) at age 24 years. Methods: Participants (n ¼ 756) from the longitudinal Nicotine Dependence in Teens study reported alcohol consumption at ages 20 and 24 years and had SBP measured at age 24 years. We examined the association between binge drinking and SBP using multiple linear regression, controlling for sex, race/ ethnicity, education, monthly drinking in high school, cigarette smoking, and body mass index. Results: Compared to nonbinge drinkers, SBP at age 24 years was 2.61 [.41, 4.82] mm Hg higher among current monthly bingers and 4.03 [1.35, 6.70] mm Hg higher among current weekly bingers. SBP at age 24 years was 2.90 [.54, 5.25] mm Hg higher among monthly bingers at age 20 years and 3.64 [.93, 6.35] mm Hg higher among weekly bingers at age 20 years, compared to nonbinge drinkers. Conclusions: Frequent binge drinking at ages 20 and 24 years is associated with higher SBP at age 24 years and may be implicated in the development of hypertension.

“…Characteristics of NDIT participants at baseline resembled those of a provincially representative sample of youth aged 13 years from the Quebec Child and Adolescent Health and Social Survey [15]. Between baseline (grade 7) and the final survey cycle in high school, 85 of the 1,294 baseline NDIT participants were lost to follow-up.…”

Do body-related shame and guilt mediate the association between weight status and self-esteem?

Individuals who are overweight or obese report body image concerns and lower self-esteem. However, little is known about the mechanisms underpinning these associations. The objective of this study was to test body-related shame and guilt as mediators in the association between weight status and self-esteem. Young adult participants (n = 790) completed assessments of self-esteem and body-related guilt and shame, and weight status indicators were measured by trained technicians. Findings from multiple mediation analyses suggest that body-related shame mediates the relationship between weight status and self-esteem. If replicated in longitudinal studies, these findings suggest that reducing body-related emotions may have important implications for improving self-esteem in clinical weight management.

“…We drew data from the longitudinal Nicotine Dependence in Teens (NDIT) Study of 1293 adolescents recruited in a purposive sample of ten public secondary schools in or near Montréal, Canada who were followed every 3 months between 7th (1999‐2000) and 11th (2004‐05) grades (total 20 cycles) . Self‐report questionnaires were administered in‐class in each data collection cycle; height, weight, and BP were measured in cycle 1 (7th grade; M [SD] age = 12.8 [0.5] years), cycle 12 (9th grade; M [SD] age = 15.2 [0.4] year), and cycle 19 (11th grade; M [SD] age = 17.0 [0.4] year).…”

Despite limited evidence on the association between physical activity (PA) and blood pressure (BP) in youth, experts recommend that adolescents engage regularly in moderate‐to‐vigorous PA. We examined the relationships between PA intensity and frequency and the likelihood of having high BP in a population‐based cohort of adolescents from Montréal, Canada. PA was self‐reported every 3 months from grade 7 to 11, and BP was measured at ages 12.8, 15.2, and 17.0 years on average. We analyzed data from 993 participants (mean [SD] age = 16.0 [1.0], 51.6% female) with BP data at ages 15.2 and/or 17.0 years, using pooled ordinal logistic regression. BP (normal/elevated/hypertensive range) was the outcome, and past‐year PA intensity and frequency were potential predictors. Eight percent of participants had elevated BP (120‐129/<80), and 3.2% had BP in the hypertensive range (≥130/≥80). Participants engaged in a median (interquartile range) of 7.0 (4.5, 9.3) and 5.5 (2, 10.8) moderate and vigorous PA sessions/week, respectively. After adjusting for age, sex, mother's education, use of alcohol and cigarette consumption, engaging in PA more intense than light during the previous year was associated with a lower odds of having BP in the hypertensive range (ORs [95% CIs] = 0.93 [0.88, 0.97] to 0.97 [0.94, 0.99]). The relationships were not altered by adjusting for BMI. Our findings support recommendations that adolescents engage in at least moderate PA on a regular basis to prevent development of BP in the hypertensive range.
