RESUMEN

BACKGROUND: Infancy and childhood are characterized by rapid growth and development, which largely determine health status and well-being across the lifespan. Identification of modifiable risk factors and prognostic factors in critical periods of life will contribute to the development of effective prevention and intervention strategies. The LucKi Birth Cohort Study was designed and started in 2006 to follow children from birth into adulthood on a wide range of determinants, disorders, and diseases. During preschool and school years, the primary focus is on the etiology and prognosis of atopic diseases (eczema, asthma, and hay fever) and overweight/obesity. METHODS/DESIGN: LucKi is an ongoing, dynamic, prospective birth cohort study, embedded in the Child and Youth Health Care (CYHC) practice of the 'Westelijke Mijnstreek' (a region in the southeast of the Netherlands). Recruitment (1-2 weeks after birth) and follow-up (until 19 years) coincide with routine CYHC contact moments, during which the child's physical and psychosocial development is closely monitored, and anthropometrics are measured repeatedly in a standardised way. Information gathered through CYHC is complemented with repeated parental questionnaires, and information from existing registries of pharmacy, hospital and/or general practice. Since the start already more than 5,000 children were included in LucKi shortly after birth, reaching an average participation rate of ~65 %. DISCUSSION: The LucKi Birth Cohort Study provides a framework in which children are followed from birth into adulthood. Embedding LucKi in CYHC simplifies implementation, leads to low maintenance costs and high participation rates, and facilitates direct implementation of study results into CYHC practice. Furthermore, LucKi provides opportunities to initiate new (experimental) studies and/or to establish biobanking in (part of) the cohort, and contributes relevant information on determinants and health outcomes to policy and decision makers.

RESUMEN

BACKGROUND: Smoking is the main preventable lifestyle-related risk factor threatening human health. In this study, time trends in smoking behaviour between 1996 and 2005 among adolescents enrolled in secondary school were assessed. METHODS: In 1996, 2001 and 2005, a survey was conducted in the south-eastern region of the Netherlands. All students in second and fourth year of secondary education (1996: n = 20 000; 2001: n = 27 500; 2005: n = 24 000) were asked to complete a questionnaire about their smoking behaviour. A simulation model was used to estimate lifetime health gains related to the observed trends. RESULTS: In 1996, 2001 and 2005, the number of questionnaires analysed were 13 554 (68%), 20 767 (76%) and 17 896 (75%), respectively. The results show a decrease in 'ever smoking' as well as 'current smoking' between 1996 and 2005. Among second year high school students, current smoking prevalence decreased from 22.2% in 1996 to 8.0% in 2005 (P(trend) < 0.001). Among fourth year students, current smoking declined from 37.5% in 1996 to 22.0% in 2005 (P(trend) < 0.001). Time trends were not influenced by gender or educational level. Model projections show that if these students not take up smoking later in life, 11 500 new cases of COPD, 3400 new cases of lung cancer and 1800 new cases of myocardial infarction could be prevented for the Dutch 13-year-olds. CONCLUSION: This study found that, in the past decade, smoking prevalence among adolescents has declined by almost 50%, potentially resulting in a considerable reduction in new cases of COPD or lung cancer.

RESUMEN

BACKGROUND: While the prevalence of childhood wheeze continues to increase in many countries, decreasing trends have also been reported. This may be explained by increased use of asthma medication, which effectively suppresses wheeze symptoms. In this study we investigated trends in wheeze in Dutch school children between 1989 and 2005, and their association with medication use. METHODS: In five repeated cross-sectional surveys between 1989 and 2005, parents of all 5- to 6-year-old and 8- to 11-year-old children eligible for a routine physical examination were asked to complete a questionnaire on their child's respiratory health. We identified all children for whom a questionnaire was completed in two successive surveys. Children were grouped according to birth year and classified into one out of four wheeze categories: "no wheeze," "discontinued wheeze," "continued wheeze," or "new-onset wheeze." RESULTS: In total, 3,339 children, born in 1983 (N = 670), 1988 (N = 607), 1992 (N = 980), and 1995 (N = 1,082), participated twice. Over the study period, the proportion of children with "no wheeze" increased from 73.8% to 86.1% (Ptrend < 0.001), while the proportion of children with "discontinued" and "continued" wheeze decreased from 13.2% to 6.3% (Ptrend < 0.001) and from 8.8% to 3.1% (Ptrend < 0.001), respectively. Medication use was consistently associated only with the presence of wheeze symptoms and this association did not change over time (Pbirth year × medication use > 0.05 for all wheeze categories). CONCLUSION: An increasing trend of Dutch school children with "no wheeze," and decreasing trends of children with "discontinued" and "continued" wheeze between 1989 and 2005 could not be explained by (increased) medication use. This suggests that wheeze prevalence is not masked by medication use, but is truly declining.
