Eating and smoking behaviours of school children in southwestern Ontario and Charlottetown, PEI.

We conducted in-class written surveys of fourth to eighth grade children's eating and smoking behaviours in southwestern Ontario (n = 870) and Charlottetown (n = 423) in order to facilitate local school boards' and health units' planning of health education initiatives. Using chi-square analysis, we examined sex, grade, provincial and rural-urban differences in behaviours. No rural-urban differences emerged. While students reported few gender differences in food group consumption, more PEI students consumed French fries, snack foods, cakes and cookies, and regular soft drinks daily. Only 60.1% (379/630) of girls and 70.0% (462/660) of boys (chi 2 = 13.8; p < 0.001) ate breakfast every day, falling to 53.2% (115/216) among eighth grade girls, and 32.9% (25/76) among students who smoked. The prevalence of smoking was 4.8% (n = 40) in Ontario and 8.5% (n = 36) in PEI (chi 2 = 6.8; p < 0.01). Compared to non-smokers, a higher proportion of students who smoked consumed snack foods and regular soft drinks daily. The results emphasize the need to promote healthy eating behaviours and anti-smoking messages among school children.     

Breakfast frequency inversely associated with BMI and body fatness in Hong Kong Chinese children aged 9-18 years

The present study assessed the relationship between breakfast frequency and measures of obesity in Hong Kong Chinese children aged 9-18 years. A total of 11,570 children (50 % boys) underwent anthropometric measurements and completed a simple self-administered dietary behaviour questionnaire. Their parents completed a questionnaire providing demographic information. Breakfast frequency was assessed by a single question, 'How many days over the past week did you have breakfast?' Children were categorised into three groups: skippers (ate breakfast 0-2 times/week); semi-skippers (ate breakfast 3-4 times/week); non-skippers (ate breakfast 5-7 times/week), to assess all associated characteristics. Of the 3644 primary and 7926 secondary school students, 8 % (8·7 % of boys and 6·9 % of girls) and 14 % (14 % of boys and 15 % of girls), respectively, were breakfast skippers. The prevalence of obesity among breakfast skippers, semi-skippers and non-skippers was, respectively, 9·8, 10·6 and 3·8 % (P < 0·001) for primary school students and 3·9, 3·1 and 2·4 % (P < 0·001) for secondary school students. The 12 % of Hong Kong children aged 9-18 years who skipped breakfast had higher BMI, BMI z-scores and percentage of body fat (PBF) than their counterparts. The dose effects of breakfast frequency (unstandardised regression coefficient, P < 0·001) on BMI and PBF were, respectively, -0·125 kg/m2 and -0·219 % for boys and -0·165 kg/m2 and -0·353 % for girls, adjusting for physical activity per additional breakfast meal per week. Further study is recommended to elucidate whether regular breakfast consumption may have a role in the prevention of childhood obesity.     

Adolescent smoking in Wuhan, China: baseline data from the Wuhan Smoking Prevention Trial

BACKGROUND: This study reports the prevalence of adolescent smoking in the urban and rural areas of Wuhan, China, the capital of Hubei Province, on the Yangtze River in central China. METHODS: Smoking behavior was examined by age, gender, and urbanicity as part of the Wuhan Smoking Prevention Trial. Subjects included 6994 seventh- to ninth-grade students attending 22 randomly selected schools in urban and rural districts. Outcome measures included lifetime smoking, past-30-day smoking, established smoking (>100 cigarettes in lifetime), and susceptibility to smoking (absence of a firm commitment not to smoke). RESULTS: Lifetime smoking prevalence was 47% among boys and 18% among girls. Past-30-day smoking prevalence was 16% among boys and 4% among girls. Established smoking prevalence was 2% among boys and 0% among girls. The prevalence of susceptibility to smoking was 31% among boys and 10% among girls. Smoking increased significantly with age (p<.0005). Susceptibility was more prevalent in rural areas than in urban areas (p<.05), but there were no urban-rural differences in lifetime, past 30-day smoking, or established smoking. Trend analyses revealed that smoking increased with age more rapidly among boys than among girls (p<.05). Smoking was more prevalent among rural boys than among urban boys, but it was more prevalent among urban girls than among rural girls (p<.05). CONCLUSIONS: Adolescent smoking is a significant public health problem in China. Boys are at particularly high risk, as are girls living in urban areas. Effective smoking prevention programs for adolescents, as well as restrictions on tobacco industry marketing and youth access to tobacco, are needed to prevent tobacco-related morbidity and mortality in China.     

Breakfast habits of different groups of Spanish schoolchildren

A questionnaire was used to investigate the schoolday and holiday breakfast habits of a group of 742 pupils (420 boys and 322 girls) aged between 9 and 13 years. The subjects attended four different schools in Madrid with populations of medium and medium–high socioeconomic level. Most pupils (53%) ate dairy products and cereals for breakfast and 10% also ate fruit: breakfasts that could be considered adequate or satisfactory. However, it was also observed that 17% of boys and 33% of girls took only dairy products at breakfast. In most cases (98%) this was limited to a glass of milk, an intake insufficient to start the day. Three per cent of boys and 5% of girls took no breakfast at all. Boys in general and the younger children of the sample spent more time at breakfast than girls or older children. They also included a wider variety of foods in their breakfasts. Most of the schoolchildren had breakfast at home (95%), either alone (42%) or with their brothers and sisters (43%). Only 25% had breakfast with their parents. Breakfast made a contribution of 15.6±0.4% to the recommended daily intake of energy. In 88% of cases, the contribution of breakfast was lower than 25% of total calories, the advisable level for this meal. During holidays the percentage of children who took no breakfast decreased to 2% of boys and 1% of girls. However, the differences observed between holidays and working days were not great. Perhaps the most important difference lies in the time spent eating breakfast, 10.8±0.3 minutes on schooldays and 20±0.6 minutes during holidays ( P <0.001). The modification of dietary habits to increase the quantity and variety of foods consumed before starting daily activity probably has a positive impact on physical and intellectual performance. It would also help in the attainment of better nutritional status and better health.     

Breakfast Consumption Suppresses Appetite but Does Not Increase Daily Energy Intake or Physical Activity Energy Expenditure When Compared with Breakfast Omission in Adolescent Girls Who Habitually Skip Breakfast: A 7-Day Randomised Crossover Trial

With concerns that adolescent girls often skip breakfast, this study compared the effects of breakfast consumption versus breakfast omission on free-living physical activity (PA) energy expenditure (PAEE) and dietary intakes among adolescent girls classified as habitual breakfast skippers. The participants went through two 7-day conditions in a trial with a crossover design: daily standardised breakfast consumption (energy content: 25% of resting metabolic rate) before 09:00 (BC) and daily breakfast omission (no energy-providing nutrients consumed) until 10:30 (BO). Free-living PAEE, dietary intakes, and perceived appetite, tiredness, and energy levels were assessed. Analyses were linear mixed models. Breakfast manipulation did not affect PAEE or PA duration. Daily fibre intake was higher (p = 0.005; d = 1.31), daily protein intake tended to be higher (p = 0.092; d = 0.54), post-10:30 carbohydrate intake tended to be lower (p = 0.096; d = 0.41), and pre-10:30 hunger and fullness were lower and higher, respectively (p ≤ 0.065; d = 0.33–1.01), in BC versus BO. No other between-condition differences were found. Breakfast-skipping adolescent girls do not compensate for an imbalance in energy intake caused by breakfast consumption versus omission through subsequent changes in PAEE but may increase their carbohydrate intakes later in the day to partially compensate for breakfast omission. Furthermore, breakfast can make substantial contributions to daily fibre intake among adolescent girls.     

Skipping breakfast among Australian children and adolescents; findings from the 2011–12 National Nutrition and Physical Activity Survey

Objective : Skipping breakfast has been linked with poor diet quality, higher BMI and adverse cardiometabolic outcomes. This study aimed to determine the prevalence and correlates of skipping breakfast among Australian children and adolescents. Methods : A total of 1,592 2–17‐year‐olds completed two 24‐hour recalls, collected via face‐to‐face and telephone interview, in the 2011–12 National Nutrition and Physical Activity Survey. Breakfast was an eating occasion of ≥210kJ named as ‘breakfast’ by the participant. Child, household and adult correlates of skipping breakfast were reported. Odds ratios were calculated using ordinal regression. Linear regression was used to examine differences in dietary intake. Survey weights were applied to give nationally representative estimates. Results : Most (86.8% of boys, 81.4% of girls) ate breakfast on both days, 11.8% of boys and 14.8% girls skipped on one day and 1.4% boys and 3.8% girls skipped on both days. Characteristics associated with skipping breakfast were being female, being older, being underweight or overweight/obese, poorer diet, lower physical activity, inadequate sleep, lower household income, greater socioeconomic disadvantage, and being from a single‐parent home. Conclusion : Skipping breakfast was common among Australian adolescents but few consistently skipped. Implications for public health : Interventions to increase breakfast should target adolescents, particularly girls, and low SEP households.     

Association between sedentary behaviour and socioeconomic factors, diet and lifestyle among the Balearic Islands adolescents

ABSTRACT: BACKGROUND: Many different factors influenced food habits and physical activity patterns of adolescents in a complex interactive way. The aim of this study was to assess association between sedentary behaviour and socioeconomic factors, diet and lifestyle among the Balearic Islands adolescents. METHODS: A cross-sectional survey (n = 1961; 12--17 years old) was carried out. Physical activity was assessed using the International Physical Activity Questionnaire for adolescents (IPAQ-A). Sedentary behaviour was defined as <300 min/week of moderate and vigorous physical activity. Anthropometric measurements, body image, socio-economic and lifestyle determinants, food consumption, and adherence to the Mediterranean diet were assessed. RESULTS: The prevalence of sedentary behaviour was 37.1% (22.0% boys, 50.8% girls). Active boys consumed frequently breakfast cereals and fresh fruit; active girls yogurt, cheese, breakfast cereals, and fresh fruit; and sedentary girls high fat foods and soft drinks. Sedentary behaviour of girls was directly associated to age, and time spent on media screen and homework, and inversely related to adherence to Mediterranean diet, and body composition. Sedentary behaviour of boys was inversely related to adherence to the Mediterranean diet, and the desire to remain the same weight. CONCLUSIONS: The prevalence of sedentary behaviour among Balearic Islands adolescents is high, mainly among girls. Age, sex, parental educational and profession levels, body size dissatisfaction, and poor quality diet are important factors of physical activity practice among adolescents.     

Cardiovascular and pulmonary risk factors in Berlin (West) schoolchildren: Findings of an exploratory study

In preparation for a comprehensive intervention project concerned with smoking behavior, physical activity, nutrition, and alcohol, an exploratory study of 800 public school and gymnasium pupils in the seventh and ninth grades (12–16 years old) was undertaken. The median of total serum cholesterol dropped from 4.8 mmol/liter in 12-year-old pupils to 4.2 mmol/liter in 16-year-olds. The decrease was greater in boys than in girls (0.7 versus 0.4 mmol/liter). The systolic and diastolic blood pressures rose slightly with age in boys and girls. The prevalence of occasional and daily smokers was 19.8 and 21%, respectively. The proportion of daily smokers was 36.4% among public school students (lower socioeconomic status) versus 4.1% among gymnasium pupils (higher socioeconomic status). Similar differences were found for the serum thiocyanate levels.     

Trajectories of Eating Behaviour Changes during Adolescence

Adolescence represents a critical transition phase during which individuals acquire eating behaviours that can track into adulthood. This study aims to characterise trends in eating behaviours throughout adolescence by investigating the presence of sub-groups of individuals presenting distinct trajectories of vegetable and fruit, sugary beverage, breakfast and fast-food consumption. Data from 744 MATCH study Canadian participants followed from 11 to 18 Years old (2013–2019) were included in the analyses. Participants reported how often they ate breakfast and consumed vegetables and fruits, sugary beverages and fast foods. Trajectories of eating behaviours over seven years were identified using group-based multi-trajectory modelling. For girls, three different groups were identified, namely ‘stable food intake with a decline in daily breakfast consumption’ (39.9%), ‘moderate food intake and worsening in overall eating behaviours’ (38.0%) and ‘stable high food intake’ (22.1%). For boys, five different groups were identified, namely ‘low food intake with stable daily breakfast consumption’ (27.3%), ‘breakfast-skippers and increasing fast food intake’ (27.1%), ‘low food intake with a decline in daily breakfast consumption’ (23.9%), ‘high food intake with worsening of eating behaviours’ (13.3%) and ‘average food intake with consistently high breakfast consumption’ (8.4%). Eating behaviours evolve through various distinct trajectories and sub-group-specific strategies may be required to promote healthy eating behaviours among adolescents.     

Breakfast consumption affects adequacy of total daily intake in children

Breakfast consumption patterns were assessed for 467 10-year-old children (59% white, 50% girls), who were interviewed in 1984–1985 or in 1987–1988. Consumption patterns were then related to mean daily nutrient intake patterns. More whites (56%) and more girls (46%) ate breakfast at home, whereas more blacks (58%) and more boys (49%) ate breakfast at school. Results indicated that 16% of all children skipped breakfast; the highest percentage was in black girls (24%). Breakfast consumption made a significant contribution to the child's mean daily nutrient intake. The average total energy intake was significantly lower for children who did not consume breakfast (mean = 1,821 kcal) and for children who consumed breakfast at home (mean = 2,098 kcal) compared with children who consumed breakfast at school (mean = 2,326 kcal). A similar pattern was noted for macronutrient contribution. Percentage of total energy from fat was lower in children who did not eat breakfast (34%) compared with those who did (37% to 39%), yet percentage of energy from carbohydrate was higher (53%) in children who did not eat breakfast. Children who skipped breakfast did not make up the differences in dietary intakes at other meals. A higher percentage of children who did not consume breakfast compared with those who ate breakfast did not meet two thirds of the Recommended Dietary Allowance for vitamins and minerals. These data confirm the importance of breakfast to overall dietary quality and adequacy in school-age children.     

Food and nutrient intakes of a population sample of 7-year-old children in the south-west of England in 1999/2000 - what difference does gender make?

OBJECTIVES: To describe the diet of schoolchildren aged 7 years, and identify gender differences in food and nutrient intakes. SUBJECTS: A cohort of children resident in the south-west of England in 1999/2000. METHODS: Diet was assessed using three 1-day unweighed food diaries. Nutrient intakes were compared with dietary reference values for this age group, and with children aged 7-10 years in the British National Diet and Nutrition Survey. Food and nutrient intakes were contrasted between boys and girls. RESULTS: Median nutrient intakes exceeded the reference nutrient intake (RNI) for most nutrients. Median intakes of iron and zinc were below the RNI. Median sodium intake was greater than the maximum set by the Scientific Advisory Committee on Nutrition. The mean energy intake for boys and girls, respectively, were 7.3 and 6.8 MJ, this is below the estimated average requirement. The percentage of energy from fat was 35.3% for boys and 36.1% for girls. Boys had higher iron intakes than girls, even after adjustment for energy intake. There were differences in the types of foods eaten between boys and girls; girls ate more fruit and vegetables (P = 0.001) and boys ate more breakfast cereals (P = 0.016). CONCLUSIONS: The dietary intakes of these 7-year-old children were adequate for most nutrients. However, a reduction in the sodium content of the diet would be advantageous. Fruit and vegetable consumption should be encouraged particularly among boys.     

The social determinants of adolescent smoking in Russia in 2004

Objectives

To determine the prevalence of adolescent smoking in the Russian Federation and examine what factors are associated with it.

Methods

Data were drawn from Round 13 of the Russia Longitudinal Monitoring Survey (RLMS) carried out in 2004. The sample consists of 815 adolescents (430 boys, 385 girls) aged 14–17 years who answered questions about their health behaviours.

Results

Smoking was more prevalent among boys than girls (26.1 vs. 5.7%). Maternal smoking and adolescent alcohol use were associated with smoking among both sexes. The self-assessment of one’s socioeconomic position as unfavourable was associated with girls’ smoking, while living in a disrupted family, physical inactivity and having a low level of self-esteem were predictive of boys’ smoking.

Conclusions

The family environment appears to be an important determinant of adolescent smoking in Russia. In particular, boys and girls may be modelling the negative health behaviour lifestyles of their parents, with unhealthy behaviours clustering. Efforts to reduce adolescent smoking in Russia must address the negative effects emanating from the parental home whilst also addressing associated behaviours such as alcohol use.

Breakfast Habits and Associations with Fruit and Vegetable Intake,Physical Activity,Sedentary Time,and Screen Time among Swedish 13–14-Year-Old Girls and Boys

This study explored whether breakfast habits were associated with intake of fruits and vegetables, minutes in moderate-to-vigorous physical activity (MVPA), minutes spent sedentary, and screen time among adolescents. Cross-sectional data were collected among 13–14-year-old boys and girls (n = 1139). Breakfast habits and screen time were determined via questionnaire, fruit and vegetable intake were determined through dietary recall, and physical activity and sedentary time were determined via accelerometers. Multilevel mixed models and general estimation equation models were applied. Almost 40% of participants skipped breakfast at least one day of the week. Participants with irregular breakfast habits on weekdays had lower fruit and vegetable consumption by 26.7 g (95% CI = −49.3, −5.9) while irregular breakfast habits during the whole week were associated with higher levels of screen time (OR = 1.5, 95% CI = 1.1, 2.1) compared to regular breakfast habits. Girls with irregular breakfast habits on weekdays had 7.7 min more sedentary time (95% CI = 0.8, 15.7) than girls with regular breakfast habits, while the opposite was found in boys (β = −13.3, 95% CI = −25.3, −2.6)). No significant associations were found for MVPA. Regular breakfast habits should be encouraged, as they might contribute to a higher intake of fruit and vegetables and are associated with lower levels of screen time, although further studies are necessary to establish causation.     

Tobacco smoking among fourth form school students in Wellington, New Zealand, 1991-97

OBJECTIVE: To investigate trends in smoking and associated demographic factors among fourth form (14-15 years) school students. METHOD: In 1991, all 35 secondary schools in Wellington, New Zealand, were invited to participate; 15 took part. Smoking behaviours were assessed biennially by self-report. Trends were examined among 5,834 students, using multilevel regression. RESULTS: When adjusted for sex, ethnicity and their interaction, the baseline (1991) prevalence of smoking within the past month was 18% (95% CI 10-29) rising to 28% (95% CI 15-46) in 1997. The comparable baseline prevalence of daily smoking was 8% (95% CI 3-21) rising to 15% (95% CI 4-40) in 1997. Smoking was more common among girls than boys and most common among Maori girls, for whom the adjusted odds of current and daily smoking were, respectively, 3.40 times (95% CI 2.56-4.52) and 5.00 times (95% CI 3.64-6.87) those of Europeans. School socio-economic status and sex composition added to the explanatory power of the model for daily smoking, but had negligible effect on the odds ratios for sex and ethnic group. CONCLUSIONS AND IMPLICATIONS: The suggested rise in the prevalence of smoking has implications for future adult smoking rates and health costs. Under-representation of socio-economically disadvantaged schools may have produced conservative estimates. The increased odds of smoking among girls and Maori confirm the need to develop interventions appropriate for these groups.     

Adolescent Physical Activity and Perceived Competence: Does Change in Activity Level Impact Self-Perception?

PurposeTo determine whether change in physical activity level impacts adolescents’ self-perceptions.MethodsUsing questionnaire responses from the Growing Up Today Study (GUTS) in 1997 and 1999, we evaluated data from 5260 girls and 3410 boys. Physical activity changes were compared to changes in perceived competence in three domains (social, athletic, and scholastic) as well as in global self-worth. Analyses controlled for sibling clustering as well as for potential confounders, including body mass index, cigarette smoking, baseline activity levels, and baseline self-perception scores.ResultsFor girls and boys, increase in physical activity was positively associated with change in social and athletic (p < .0001), but not scholastic or global, self-perception. Compared to those with little or no change in activity, those who increased physical activity were more likely to have increased self-perception measures. Girls who increased physical activity by 5 or more hours/week were at least 33% more likely to have increased social self-perception, and at least 44% more likely to have increased athletic self-perception. In boys, those who increased activity by 10 or more hours/week were 45% more likely to have increased social self-perception. The reverse was also true; for both girls and boys, those with decreased physical activity were more likely to have decreased self-perception scores.ConclusionsThis research indicates that increased physical activity has a positive impact on athletic and social self-perception in girls and boys.     

Early determinants of smoking in adolescence: a prospective birth cohort study

In a prospective birth cohort study in Brazil, the prevalence and early risk factors for smoking in adolescence were investigated. All 1982 hospital-born children in Pelotas, Rio Grande do Sul, Brazil, were enrolled in a birth cohort study (N = 5,914; boys: 3,037; girls: 2,877). All male participants were searched in 2000 when enrolling in the national army, and 78.8% were traced. In 2001, a systematic sample of 473 girls was interviewed, representing a follow-up rate of 69.1%. Among males, 48.6% (95%CI: 46.6-50.7) had ever tried smoking and 15.8% (95%CI: 14.3-17.3) were daily smokers. Among females, 53.1% (95%CI: 48.6-57.6) had ever tried smoking and 15.4% (95%CI: 12.1-18.7) were daily smokers. Boys born to single mothers and those with fathers with low schooling were more likely to smoke in adolescence. Girls from low-income families, with mothers who smoked during pregnancy, and fathers with alcohol-related problems were more likely to smoke. Although the smoking prevalence was similar in boys and girls, risk factors for smoking were different between the sexes. Social environment appears to be the strongest predictor of tobacco use in adolescence.     

Health among teenagers and young adults

The objective of this article is to analyse different behaviours and opinions about health and health determinants of Spanish young people by age, sex, and place of residence. They have a broad concept of their health, tending to identify health as physical activity and healthy eating behaviours. Most of them (91%) declared enjoying good or very good health. Depending upon the age, sex, and place of residence 10 to 20% could have mental health problems. Young people consider illegal drugs as their main health problem. Boys have higher prevalence of overweight and obesity than girls. However, girls reported more often than boys that they perceived themselves as obese. Practice of sporting activities is influenced by family and friends. The proportion of young people that practice sport declines after the age of 15, both in boys and girls. Young people perceive cannabis consumption as normal, but remain ambivalent towards other illegal drugs and asked for more information about drugs. We found a high proportion of young people declaring that they not would try illegal drugs. In the urban settings, smoking is more common among girls than among boys, but the contrary happens in rural areas. Most of them know that smoking is harmful for health, and among those who are smokers, 20 to 40% declared that they want to stop smoking. They consider that health care services are useless for preventing health problems. It is necessary to improve behaviours involving safety, such as use of seat belts and helmets, mainly in rural areas. Young people associated traffic accidents with driving conditions rather than with identification of risk.     

Weight status, energy-balance behaviours and intentions in 9–12-year-old inner-city children

Background:  Dutch youth health care promotes four so-called energy-balance behaviours for the prevention of obesity: increasing physical activity, reducing sedentary behaviour and sugar-containing drinks, and eating breakfast. However, data on the prevalence of these behaviours and intentions to engage in them among primary schoolchildren is limited, especially for multi-ethnic, inner-city populations. The present study aimed to provide these data and explore differences according to socio-demographic characteristics and weight status.
Methods:  Data on behaviours and accompanying intentions were collected using classroom questionnaires. Stature and body weight were measured by trained staff. Twenty primary schools in Rotterdam participated. Data on 1095 9–12 year olds (81.7% response rate) were available for analysis. Multiple logistic regression analyses were conducted to determine associations between behaviours (favourable or unfavourable), intentions (positive or not), gender, age, ethnicity, neighbourhood income level and weight status.
Results:  The prevalence of being overweight was 30.4%, including 9.0% obesity. Engagement in energy-balance behaviours varied from 58.6% for outdoor play (>1 h previous day) to 85.9% for active transportation to school (day of survey). The highest positive intentions were reported for taking part in sports (83.9%), and lowest for reducing computer time (41.3%). Small differences in behaviours and intentions according to socio-demographic characteristics were found, most notably a lower engagement in physical activity by girls. Skipping breakfast and total number of energy-balance behaviours were associated with being overweight.
Conclusions:  The prevalence of being overweight among Dutch inner-city schoolchildren is high. A general rather than a differentiated approach is needed to improve engagement in energy-balance behaviours among inner-city schoolchildren.
