[Tobacco Use and Utilization of Medical Services in Adolescence: An Analysis of the KiGGS Data]. / Tabakkonsum und Inanspruchnahme medizinischer Leistungen im Jugendalter ­ Eine Analyse der KIGGS Daten.

OBJECTIVE: In Germany, there is a lack of information on the correlation between tobacco use by adolescents and their utilization of medical care. The aim of this article is to identify possible early consequences of adolescent smoking. METHODS: We conducted a re-analysis of cross-sectional data of the baseline wave (2003-2006) of the German Health Survey for Children and Adolescents (KiGGS). To examine the association between current smoking status and utilization of medical care during the 12 months before the interview, prevalence of selected diseases was calculated, and stratified by smoking status. Besides, the proportion of adolescents who consulted a physician at least once and the total number of medical consultations were estimated. For the inpatient setting, information about the number of nights spent in a hospital was analyzed. In a multiple logistic regression, the association of smoking behavior with utilization of outpatient medical care was assessed, further adjusting for sociodemographic variables and comorbidities. RESULTS: The study population included 3 679 adolescents aged between 14 and 17 years. 49.1% were female and 31.7% were current smokers. Among smokers, there was an increased prevalence of cystitis (+87.0%) and bronchitis (+50.0%). Tobacco users consulted a general practitioner more frequently than non-smokers (+30.8%). As far as medical specialists are concerned, there were more consultations with psychiatrists (+171.4%) and psychologists (+94.4%), but there was no increase in the total number of visits. Additionally, smoking adolescents were more frequently hospitalized (+26.5%) and the stays were of longer duration (+19.7%). There was a statistically significant association between current tobacco use and a greater utilization of medical care (OR=1.20; 95%-CI: 1.02-1.40). CONCLUSIONS: Tobacco use among adolescents was associated with increased prevalence of certain diseases and a greater utilization of medical care. Nevertheless, whether there is a causal connection is still debatable. The KiGGS cohort study will provide opportunities to further clarify the observed association.

Incidence of pneumonia in nursing home residents in Germany: results of a claims data analysis.

Pneumonia is one of the most common infectious diseases with a high mortality, especially in the elderly population. To date, there have been only a few population-based studies dealing with the incidence of pneumonia in nursing homes (NHs). We conducted a cohort study using data from a large German statutory health insurance fund. Between 2010 and 2014, 127 227 NH residents 65 years and older were analysed. For the calculation of incidences per 100 person-years (PY) and 95% confidence intervals (CIs), we assessed the first diagnosis of pneumonia during the time in NH. We compared the rates between sexes, age groups, care levels, and comorbidities and we performed a multivariate Cox regression analysis. The mean age in the cohort was 84.0 years (74.6% female). A total of 19 183 incident cases led to an overall 5-year-incidence of 11.8 per 100 PY (95% CI 11.7-12.0). The incidence in men was substantially higher than in women. Rates were highest in the first month after NH placement. Our study revealed that the incidence of pneumonia is high in German NH residents and especially in males. Due to demographic changes, pneumonia will likely be increasingly relevant in the health care of the elderly and institutionalised population.
