Background
Distorted body image plays a significant role in the development of obesity, eating problems, and eating disorders. The aim of this study was to investigate the relationship between distorted body image and lifestyle among Japanese adolescent boys and girls.Methods
Subjects were 1731 seventh graders (age 12–13 years) from the Ina-town’s junior high schools, Japan, from 2005–2009. The height and weight of each subject were measured. Childhood underweight, overweight, and obesity were defined using the body mass index cutoff points proposed by the International Obesity Task Force. Information regarding the self-perceived weight status and lifestyles (exercise, snacking after dinner, breakfast, wakeup time, bedtime) of each subject was collected using a self-administered questionnaire. Self-perceived weight status was categorized into three groups (thin, normal, or heavy), and compared with the subjects’ actual weight status. Body image perception was categorized into the following three groups: an underestimated own weight status group (underestimated group), a correct own weight status group (correct group) and an overestimated own weight status group (overestimated group).Results
The proportion of boys in the underestimated group was higher than that of girls, while the opposite was true for the overestimated group (P < 0.001). There were no statistically significant differences in lifestyle between the underestimated group and the correct group regardless of sex. In contrast, there were statistically significant differences between the overestimated group and the correct group in the lifestyle factors of exercise among boys and snacking after dinner among girls. The adjusted odds ratio (OR) in boys who exercised daily significantly decreased (OR: 0.35, 95 % CI: 0.16–0.77), while a significantly increased OR was observed in girls who snacked after dinner (OR: 1.53, 95 % CI: 1.07–2.19).Conclusion
Adolescent boys tended to underestimate their body weight, whereas adolescent girls were likely to overestimate their body weight. Furthermore, lifestyle factors associated with distorted body image differed by sex, with exercise affecting body image perception among boys and snacking after dinner affecting body image perception among girls. Thus, lifestyle may lead to distorted body image among adolescents. 相似文献3.
PURPOSE: We investigated the contributions of individual, family, and community-level factors for explaining alcohol use and smoking among rural Mexican adolescents. METHODS: As part of a national survey, 3922 adolescents and their mothers from 333 poor, rural communities in seven Mexican states provided cross-sectional data on family-level, socioeconomic, and psychosocial factors, and individual-level data on substance use and psychological symptoms. Community standard of living was also assessed. RESULTS: Generalized linear models adjusted for sampling design indicated that adolescents' use of alcohol was associated with being male, older, employment, and having a mother who used alcohol. Being from an indigenous family living in a majority-indigenous community was associated with less alcohol use. Family income, family size, and community standard of living were not directly associated with adolescents' alcohol use. Current smoking was associated with being male, older, and more anxious, having a mother who smoked, and having a mother with higher educational attainment. Further analyses indicated patterns in which adolescents' alcohol use was moderated by gender and ethnicity. CONCLUSIONS: Beyond the contribution of male gender and age as risk factors, maternal substance use uniquely explained variability in alcohol and cigarette use among Mexican adolescents from rural communities. Indigenous ethnicity and living in majority-indigenous community settings appeared to confer protective benefits with respect to alcohol. These findings extend prior research in Mexico and in other countries that identify the combined importance of developmental contexts and individual-level factors for adolescent health. 相似文献

Despite data that the rate of boys' cigarette use has declined nationwide, boys' total tobacco use may actually have remained high because of their substantial use of smokeless tobacco. We surveyed anonymously a random sample of entire classes of grade 7-12 boys and girls from 59 Connecticut towns concerning tobacco use. Despite girls' higher daily cigarette use, boys' total daily tobacco use was higher than that of girls in grades 7-9, and only slightly lower in grades 10-12. 相似文献

BACKGROUND: Adolescent tobacco use has been a serious public health issue, resulting in longer duration of tobacco use and higher nicotine dependence in adulthood. This study identified the current status of tobacco use among middle schools students in Jeddah, Saudi Arabia and the factors leading to tobacco use, to provide information on how to effectively prevent tobacco use among adolescents. METHODS: A cross‐sectional survey was administered to measure the prevalence of tobacco use and profile tobacco users. School selection was stratified by region, gender, and type (public or private). Altogether, 1186 seventh‐ to ninth‐grade students were selected. Of those, 1019 questionnaires were used for analysis. RESULTS: The mean age of the participants was 14.3 years (SD = 1.2) and boys comprised 54% of the sample. The prevalence of tobacco use among students was 9.72% with a significant difference between sexes (12.43% for boys and 6.65% for girls). Bivariate and multivariate analyses results showed that students whose families had higher income, had larger daily allowances, spent less time studying, skipped class more frequently, were less religious, spent more time out of home, drank more Coca‐Cola, intended to use tobacco in the next year, and were males who were more likely to use tobacco. CONCLUSION: Prevention programs designed to reduce adolescent tobacco use need to consider these sociodemographic characteristics. Understanding the characteristics of adolescent tobacco users and the associated sociocultural context is critical for developing effective tobacco prevention programs targeted at adolescents. 相似文献

OBJECTIVE: To examine the association between behavioral problems and tobacco smoking among adolescent students in Chile. METHODS: Data were drawn from a study that included questionnaire surveys of 46 907 school-attending adolescents in all 13 of the administrative regions of Chile. Assessments were based on an adapted, Spanish-language version of the Drug Use Screening Inventory. The conditional form of the logistic regression model was used for analysis, with matching of students on individual schools, and with further statistical adjustments for sex, age, and selected risk factors. RESULTS: The prevalence of tobacco smoking among the adolescents was very high across all of Chile, with a level between 56% and 65% in each of the 13 regions. The estimated odds of tobacco use in youths at the highest level of behavioral problems was about twice that for youths at the lowest levels, both before and after controlling for sex, age, lack of participation in recreational activities, level of irritability, and levels of problems with school, family attention, and mental health. CONCLUSIONS: These findings help to complement and complete the evidence of prior studies on tobacco smoking among adolescents with behavior problems, including recent research on Central American youths. Although the magnitude of observed associations in Chile was not as great as that for the associations found in Central America, both the strength of these associations and their statistical significance were observed throughout Chile. This is the first study in Chile on potentially causal relationships such as these. 相似文献

Data from a 2-year study describe tobacco use trends, perceptions, and prevention effects for 1,281 5th and 6th graders enrolled in 12 randomly selected Washington State elementary schools. Youths were pretested, then randomly divided by school into skills, discussion, and control groups. Preventive intervention curriculums for the skills and discussion groups included age-relevant information on smoked and smokeless tobacco use, peer testimonials, debates, games, and homework. Youths in the skills group also learned communication and problem-solving methods for handling difficult situations around tobacco use. Following intervention, youths were posttested, then retested semiannually for 2 years. During the 2-year study, three-quarters of all smokers and nonusers and half of all smokeless tobacco users maintained their statuses. Only 10 percent of all smokers and 3 percent of all smokeless users quit their habits. One in six reported new tobacco use, one-third of smokers began using smokeless tobacco, and two-thirds of all smokeless users began smoking during the study. Most youths at final measurement perceived smokeless tobacco as less of a health risk than smoking. Nearly one in two of all smokeless users intended to smoke, and two-thirds were actually smoking at 24-month followup. Both smoked and smokeless tobacco use rates increased in all groups, and youths in the skills intervention group consistently showed the lowest rates relative to the other groups. These findings demonstrate the potential of skills intervention methods for lowering tobacco use rates among adolescents. 相似文献

Although cigarette and smokeless tobacco use are recognized as major problems among school-age youth, few nationwide or statewide data exist on the prevalence and patterns of use. To determine the patterns of tobacco use among children and adolescents in Missouri, self-report information was obtained from a representative sample of 5,431 students in grades 5, 8, and 12. Both cigarette smoking and smokeless tobacco use were more common among males than females for each grade level except the 12th, where 30% of females and 28% of males had smoked during the previous week. Smoking prevalence was considerably lower among blacks than whites. Smokeless tobacco use was rare among both blacks and females. Smokeless tobacco use was more common than cigarette smoking in rural areas, where 17% of 8th-grade males and 31% of 12th-grade males had used smokeless tobacco during the previous week. The mean age at first use of cigarettes was slightly lower in the rural than the urban area, whereas the mean age of initial smokeless tobacco use was more than a year earlier in the rural area. Data regarding the perceived difficulty of quitting smoking and quit rates suggested that adolescent females have more difficulty quitting smoking than males. Male smokeless tobacco users appeared to be more addicted than male cigarette smokers. Smokeless tobacco brand preference indicated that users may switch to progressively stronger types of smokeless tobacco as they get older and a nicotine tolerance is developed. The current study emphasizes the urgent need for carefully targeted tobacco prevention and cessation efforts among school-age youth. 相似文献

PURPOSE: To examine how saturation of an adolescent's environment with models of cigarette smoking (e.g., parents, siblings, friends) affects the probability of tobacco and alcohol use among junior high and high school students. METHODS: The Health and Smoking Questionnaire was administered to 806 adolescents (182 smokers and 624 nonsmokers; 57.2% female) average age of 15.1 years (SD = 1.6) in a mid-size Midwestern town. The questionnaire contains standardized items in five domains: demographics, smoking status and history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style. RESULTS: Risk for smoking or using alcohol increased dramatically as the number of models who smoke increased in an adolescent's environment. For instance, adolescents with one significant other who smoked were nearly four times (OR = 3.76, p <.001) more likely to smoke than someone with no significant others who smoked. However, if an adolescent had four significant others who smoked, they were over 160 times more likely to smoke (OR = 161.25, p <.001). Similar results were found for alcohol use; adolescents who had one significant other who smoked were more than 2.5 (OR = 2.66, p <.001) times more likely to drink than those without smoking models. Adolescents who had four significant other smoking models were 13 times (OR = 13.08, p <.001) more likely to drink. CONCLUSIONS: As the number of cigarette smokers in an adolescent's environment increases, risk of tobacco and alcohol use increases substantially. These data suggest that multiple models of tobacco use will substantially increase risk for substance use in adolescents. 相似文献

This paper investigates the relationship between antisocialbehaviour and injury-related behaviour in a sample of youngNorwegian males and females. The results indicated that antisocialbehaviour was positively related to risk-seeking behaviour andnegatively related to safety-seeking behaviour. The associationswere similar for both genders. The findings suggest that thedisproportionate level of injuries among antisocial and delinquentadolescents, which are reported in numerous studies, may beaccounted for by their high level of risk-seeking activity andlow level of safety-seeking activity. 相似文献
