Early-life use of antibiotics is associated with asthma. We examined the effect of antibiotic use for early-life bronchiolitis on the development of new-onset asthma in children from Taiwan between 2005 and 2010. Data were from the National Health Insurance Research Database 2010, and diseases were coded using the International Classification of Disease (ICD). We classified the patients, all of whom had bronchiolitis, as having asthma or not having asthma. Asthma was diagnosed using ICD criteria and by use of an inhaled bronchodilator and/or corticosteroid twice in one year. We identified age at asthma onset, sex, residential area, history of atopy and NSAID use, age at first use of antibiotics, and the specific antibiotic, and adjusted for these factors using conditional logistic regression analysis. Among all individuals, there was a relationship between risk of new-onset asthma with use of a high dose of an antibiotic (adjusted odds ratio [aOR] = 3.33, 95% confidence interval [CI] = 2.67–4.15). Among the different antibiotics, macrolides (aOR = 2.87, 95% CI = 1.99–4.16), and azithromycin specifically (aOR = 3.45, 95% CI = 1.62–7.36), had the greatest effect of development of asthma.

The health costs of colorectal cancer have increased over the years in Taiwan. The National Health Insurance Administration (NHI) and the Health Promotion Administration of the Ministry of Health and Welfare (MOHW) in Taiwan advocate that people have to change their unhealthy behaviors; however, the number of patients of colorectal cancer is increasing annually. This research discussed the effects of healthy diet advocacy advertisements (ads) on healthy diet behavior intentions as influenced by the interactions between regulatory focus theory (RFT) and message framing effects. Both regulatory focus theory and message framing effect were discussed for the relationship between advertisement and behavior change in many fields, such as health-related behavior, pro-environmental behavior, consumer choice, etc. We executed an experiment with four different types of public health advocacy ads. A 2 (regulatory focus: promotion vs. prevention) × 2 (message framing: gain framing vs. loss framing) two-factor experiment was adopted, and 201 valid participants responded to the questionnaire. Results indicated that if the ad’s regulatory focus is promotion focus, viewers’ attitudes toward the ad and their behavior intentions are more positive when the slogan of the ad is gain framing rather than loss framing via the multiple analysis of variance (MANOVA), and vice versa. Respondents found the communication easier to comprehend when the ads evoked the respondents’ regulatory focus and applied the appropriate message framing, thus improving the efficacy of health-related advertising. We offer suggestions regarding the future use of health-related advertising for the MOHW.

Both breast cancer and autoimmune diseases (ADs) are predominant in women. NSAIDs are common medications for AD. Evidence on the association between NSAIDs use and breast cancer risk is controversial. We investigated the association between NSAIDs exposure and breast cancer risk in female patients with AD. AD patients older than 18 years of age were enrolled from Taiwan Longitudinal Health Insurance Database 2005. The NSAID users were defined as AD patients who had ever taken NSAIDs for at least 3 months between 2000 and 2009. All individuals were followed from the date of first diagnosis of AD to the end of 2013 to evaluate the risk of breast cancer. We estimated the adjusted hazard ratio (HR) using Cox proportional hazard regression after adjusting for age, comorbidities and medications. A total of 12 331 NSAID users and 12 331 non-NSAID users were included in this study after 1: 1 individual matching. The NSAID users were less likely to develop breast cancer than the non-NSAID users (adjusted HR: 0.37; 95% confidence interval: 0.27–0.50; P < 0.001), even if they used NSAIDs with low cumulative defined daily doses (adjusted HR: 0.42; 95% confidence interval: 0.34–0.53; P < 0.001). The incidence of new-onset breast cancer in NSAID users was significantly decreased in users taking selective cyclooxygenase 2 inhibitors, diclofenac, ibuprofen and piroxicam. Lower cumulative hazard rates were found in the AD patients who used NSAIDs (P < 0.001). NSAID exposure is associated with a decreased risk of breast cancer in female AD patients.
