This analysis examines self-perceived health among Canadian adolescents aged 12 to 17, and factors associated with ratings of very good/excellent health.
The data are from cycle 1.1 of the 2000/01 Canadian Community Health Survey (CCHS), conducted by Statistics Canada. The sample consisted of 12,715 adolescents aged 12 to 17.
Cross-tabulations were used to estimate the prevalence of various characteristics and health behaviours for the 12-to-14 and 15-to-17 age groups. Multiple logistic regression was used to model associations between very good/excellent self-reported health and selected characteristics.
In 2000/01, nearly 30% of 12- to 17-year-olds rated their health as poor, fair or good. At ages 15 to 17, girls were less likely than boys to report very good/excellent health and were more likely to have a chronic condition and to have experienced depression in the past year. When other factors were taken into account, the odds of reporting very good/excellent health were significantly lower for teens who were daily smokers, episodic heavy drinkers, physically inactive during leisure time, infrequent consumers of fruit and vegetables, or obese, compared with teens who did not have these characteristics.
To provide a systematic review of physical activity intervention research conducted with adolescent girls (12-19 years of age and/or in middle or high school) in the United States and Canada during the past two decades.
Published articles in English were identified in searches using MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycLIT, EMBASE, Science Citation Index, and the Cochrane Controlled Trials Register, with the keywords adolescent health, obesity, physical activity, and exercise, between the dates of May 1980 and November 2003.
Research studies with interventions that started within the adolescent time period. Only 7 studies met the inclusion criteria.
The publication year, sample description, study design, interventions used, and outcomes were extracted from each study.
The 7 studies were published between 1989 and 2003, included girls and boys in the overall sample (no studies with girl-only samples), used randomized controlled trial or quasi-experimental designs, and included multicomponent interventions. Body mass index, fitness levels, exercise, and weight were measured as outcomes.
Although the results were not consistent across studies, they suggest that school-based, multicomponent interventions that were also designed to decrease sedentary behavior were effective in increasing physical activity in adolescent girls. Future research should focus on determinants of long-term adherence and the duration and intensity of interventions necessary to prevent obesity in adolescent girls.
To investigate meal pattern longitudinally and explore whether meal skipping was associated with overweight among Norwegian children and adolescents.
Longitudinal study. Children's meal frequencies were reported by their parents using a retrospective FFQ. Weight and height were measured by public health nurses. Descriptive data comparing 4th and 7th grade were analysed by paired-sample t tests for continuous variables and ? 2 tests for categorical variables. Odds ratio estimates, including confidence intervals, with BMI category (normal/overweight) as the dependent variable, were determined through logistic regression analyses.
Primary schools, Telemark County, Norway.
A cohort of 428 Norwegian boys and girls; 4th graders in 2007, 7th graders in 2010.
The number of children eating four main meals per day (regular meal frequency) decreased from 4th grade (47 %) to 7th grade (38 %; P = 0·001). Those who ate regular meals in 4th grade but not in 7th grade had higher odds (OR = 3·1; 95 % CI 1·1, 9·0) of being overweight in 7th grade after adjusting for gender, maternal education and physical activity, but the odds ratio was not statistically significant after adjusting for overweight in 4th grade (OR = 2·8; 95 % CI 0·7, 11·6).
The present study showed significant increases in overall meal skipping among children between 4th and 7th grade. The results indicate an association between overweight and meal skipping, but additional prospective and longitudinal analyses and intervention trials are warranted to confirm this relationship.
To assess the nutritional status of Tarahumara children at indigenous boarding schools.
Cross-sectional comprehensive nutritional survey.
The schools sampled were located in indigenous municipalities of the northern Mexican state of Chihuahua.
The study was carried out in 2001 among 331 children aged 6-14 y from a sample of five schools. Anthropometric measurements, a thyroid exam and capillary haemoglobin levels were obtained from the children. Serum concentrations of ferritin, iron, total iron-binding capacity, vitamin B(12), folic acid and zinc were collected from a subsample of 100 children.
The prevalence of wasting and overweight (children 6-9 y) was 1.1 and 4.6%, respectively, and of underweight, risk of overweight and overweight (10-14 y) was 3.2, 5.1 and 0.6%, respectively. Stunting (6-12 y) was present in 22.3% of the children. The total goitre rate was 5.4%. The prevalence of anaemia was 13% (boys 11.4, girls 14.5%). Overall, 24.2% of the children were iron deficient (depletion 11.1%, deficient erythropoiesis 3%, iron deficiency anaemia 10.1%). No child had folic acid values
