Changing prevalence of asthma in Taiwanese adolescents: two surveys 6 years apart

PEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 2 2005
Yung-Ling Lee
This study compared the prevalence of asthma among Taiwanese adolescents with individual-level risk factors and municipal-level air pollution and meteorology data to determine whether changes in these factors could explain the observed change in prevalence. We conducted two national surveys of respiratory illness and symptoms in Taiwanese middle-school students in 1995,96 and 2001. The effects of personal and environmental factors were assessed and temporal changes of outdoor monitoring data were also compared with asthma prevalence difference. A total of 44,104 children from the 1995,96 survey and 11,048 children from the 2001 survey attended schools located within 1 km of 22 monitoring stations. Lifetime prevalences of physician-diagnosed and questionnaire-determined asthma increased during this period. After adjustment for potential risk factors, the prevalence differences were statistically unchanged. Although parental education level contributed most, changes in investigated personal and environmental factors might not explain the observed changes in asthma prevalence. Municipalities with higher temperature increase were significantly associated with prevalence difference in questionnaire-determined asthma. We concluded that correlates of the investigated individual-level factors, which have changed over time, still underlie changes in asthma prevalence. Increasing temperature might be the main reason for the rising trends of asthma in Taiwanese adolescents. [source]

Disturbed eating behaviors in Taiwanese adolescents with type 1 diabetes mellitus: a comparative study

PEDIATRIC DIABETES, Issue 1 2009
Yu-Yun Alice Hsu
Objectives:, This study aimed to (i) compare disturbed eating behaviors in adolescents with type 1 diabetes mellitus (T1D) with a matched group of adolescents in Taiwan and (ii) examine the relationships of disturbed eating behaviors to body mass index (BMI) and metabolic control among adolescents with T1D. Methods:, A cross-sectional study was conducted in southern Taiwan. Seventy-one adolescents with T1D (aged 10,22 yr; 41 females and 29 males) were matched to a group of non-diabetic adolescents. Adolescents completed two self-reported measures of eating behavior, the Bulimic Investigatory Test, Edinburgh and the Eating Attitude Test-26. Metabolic control was assessed by glycosylated hemoglobin A1c levels. Results:, Both adolescent females and males with T1D had more symptoms of bulimia and bulimic behaviors than their non-diabetic peers. There were no group differences in the proportion of subthreshold eating disorders. BMI and metabolic control were significant factors predicting disturbed eating behaviors. Conclusions:, Both adolescent females and males with T1D exhibited a higher level of disturbed eating behaviors than their non-diabetic adolescent counterparts. Preventive programs that address disturbed eating behaviors should be provided for adolescents with T1D, particularly for adolescents with a high BMI and poor metabolic control. [source]

Determinants of physical activity among Taiwanese adolescents: An application of the health promotion model,

RESEARCH IN NURSING & HEALTH, Issue 1 2002
Tsu-Yin Wu
Abstract The purpose of this study was to examine the relationships among interpersonal influences (i.e., social support, norms, modeling), behavior-specific cognitions (i.e., self-efficacy, perceived benefits/barriers), competing demands, and physical activity among Taiwanese adolescents (N,=,832). The results from structural equation modeling indicated that perceived self-efficacy was the most important predictor of physical activity. Interpersonal influences, when considered in total, had a weak and nonsignificant direct effect on physical activity but had indirect effects on physical activity thorough perceived benefits and perceived self-efficacy. When sources of interpersonal influences were considered separately, parental influences did not have direct effects on physical activity. In contrast, peers did have a significant direct effect on physical activity and also indirect influences on physical activity through perceived self-efficacy. All variables accounted for 30% of the variance in physical activity. Results of this study identify important influences useful to health professionals for promoting physical activity in this population. © 2002 John Wiley & Sons, Res Nurs Health 25:25,36, 2002.

Increasing prevalence of atopic eczema in Taiwanese adolescents from 1995 to 2001

CLINICAL & EXPERIMENTAL ALLERGY, Issue 4 2007
Y.-L. Lee
Summary Background The prevalence of atopic eczema in adolescents has recently been reported as increasing in many countries, a phenomenon yet to be fully explained. This study compared the prevalence of atopic eczema among Taiwanese adolescents with individual-level risk factors and community-level data of temperature, relative humidity, and air pollutants to determine whether changes in these factors could explain the observed change in prevalence. Methods We conducted two nationwide, cross-sectional surveys of atopic illness and symptoms among Taiwanese 12,15-year-old schoolchildren in 1995,1996 and 2001. The effects of personal and environmental factors were assessed and temporal changes of outdoor monitoring data were also compared with the prevalence difference of atopic eczema. Results A total of 42 919 adolescents from the 1995 to 1996 survey and 10 215 adolescents from the 2001 survey attended schools located within 1 km of 22 monitoring stations. The 12-month prevalence of atopic eczema increased significantly during this period [adjusted prevalence ratio (PR)=1.43, 95% confidence interval (CI) 1.21,1.70 in boys; PR=1.77, 95% CI 1.49,2.10 in girls]. After adjustment for potential risk factors, the prevalence differences were statistically unchanged. Although parental education level contributed the most, changes in personal and environmental factors might not explain the observed prevalence increases of atopic eczema. Temporal change in the relative humidity was significantly associated with prevalence increase among boys but its contribution was also small. Conclusion Correlates of the investigated risk factors that have changed over time still underlie the prevalence increases of atopic eczema in Taiwanese adolescents. The exact reasons for the rising trends remain to be elucidated. [source]
