BackgroundCaregiver health is a crucial public health concern due to the increasing number of elderly people with disabilities. Elderly caregivers are more likely to have poorer health and be a care recipient than younger caregivers. The Taiwan government offers home-based long-term care (LTC) services to provide formal care and decrease the burden of caregivers. This study examined the effects of home-based LTC services on caregiver health according to caregiver age.MethodsThis cross-sectional study included a simple random sample of care recipients and their caregivers. The care recipients had used LTC services under the Ten-Year Long-Term Care Project (TLTCP) in Taiwan. Data were collected through self-administered questionnaires from September 2012 to January 2013. The following variables were assessed for caregivers: health, sex, marital status, education level, relationship with care recipient, quality of relationship with care recipient, job, household monthly income, family income spent on caring for the care recipient (%) and caregiving period. Furthermore, the following factors were assessed for care recipients: age, sex, marital status, education level, living alone, number of family members living with the care recipient, quality of relationship with family and dependency level. The health of the caregivers and care recipients was measured using a self-rated question (self-rated health [SRH] was rated as very poor, poor, fair, good and very good).ResultsThe study revealed that home nursing care was significantly associated with the health of caregivers aged 65 years or older; however, caregivers aged less than 65 who had used home nursing care, rehabilitation or respite care had poorer health than those who had not used these services. In addition, the following variables significantly improved the health of caregivers aged 65 years or older: caregiver employment, 20% or less of family income spent on caregiving than 81%–100% and higher care recipient health. The involvement of daughters-in-law, rather than spouses, and care recipient health were positively related to the health of caregivers aged less than 65 years.ConclusionsThe findings suggest that home-based LTC service use benefits the health of elderly caregivers. By contrast, home-based LTC service use may be negatively correlated with the health of the caregivers aged less than 65 years.Electronic supplementary materialThe online version of this article (10.1186/s12955-017-0786-6) contains supplementary material, which is available to authorized users.

Accurate identification of smoking behaviour is crucial to monitor the smoking rate. This study used urinary cotinine (UC) as a biomarker to verify the effectiveness of self-reported smoking behaviour among conscripts during recruit training. The influence of second-hand smoke (SHS) on the UC concentration was also analysed. A cross-sectional study was conducted from July 2014 to December 2014. The participants comprised a total of 621 military service and basic military training conscripts. A self-administered questionnaire survey and a urine test were performed to verify the participants' smoking behaviour. The UC concentration of 100 ng/mL was adopted as the baseline to identify smokers. A high level of consistency was observed between the conscripts' self-reported results and the results validated by the UC concentrations (the overall kappa coefficient was 0.918). Moreover, the overall sensitivity and specificity were 92.9% and 98.1%, respectively. The sensitivity for the military service conscripts was significantly lower than that for the basic military training conscripts (86.1% vs. 97.5%, P-value = 0.002). For the self-reported nonsmokers among the military service conscripts, SHS exposure was related to their UC concentrations. The method of self-reporting through a questionnaire survey can serve as a tool to assess conscripts' smoking behaviour.Tobacco has been proven to be harmful to human health. Research on tobacco hazards has reported that smoking induces numerous diseases such as chronic lung disease and lung cancer 1 . The general smoking status of various groups should be understood before the implementation of tobacco hazard prevention strategies. Thus, the smoking rate is a crucial indicator for tobacco hazard prevention, which can be determined through the self-reporting of smokers or using biomarker concentrations in those smokers. Cotinine is a major metabolite of nicotine and can be detected in blood, saliva, and urine samples 2,3 . In particular, urinary cotinine (UC) concentration is an easily obtainable and highly effective biological indicator for smoking 4 . Previous review study have reported that the method of self-reporting, compared with biomarker approaches, may underestimate the smoking rate, and the extent of underestimation varies according to the research participants' attributes 5 . In Canada, a large, nationwide survey revealed that the self-reported smoking rate of the country was 18.8%; in comparison, the smoking rate determined through the UC concentrations was reported to be 19.1%. Although, the self-reported smoking rate was underestimated, the two results were highly consistent. The sensitivity and specificity of the self-reported smoking rate was 91.6% and 98.3%, respectively 6 . However, studies on specific groups, such as pregnant women and patients with chronic obstructive pulmonary disease, showed that the self-reported smoking rate was significantly lower than that derived using the UC concentrations [7][8][9][10] . This might be attributable to the ways in whic...

Smoking rates in the military are evaluated through questionnaire surveying. Because the accurate identification of smokers facilitates the provision of smoking cessation services, this study conducted urine cotinine concentration testing to verify the accuracy of self-reported smoking behavior by female volunteer soldiers and analyzed the effects of second-hand smoking on urine cotinine concentrations. This study is a cross-sectional study conducted using purposive sampling on female volunteer soldiers receiving training at the Taichung Recruit Training Center in May 2014. This study simultaneously collected questionnaires and urine samples, and urine samples were analyzed with an enzyme-linked immunosorbent assay. The self-reported smoking rate of female volunteer soldiers was 19.3%, whereas the smoking rate as determined by urine cotinine concentration testing was 26.3%, indicating an overall underestimation of 7.0%. Chi-square (χ2) goodness of fit test results indicated that the distribution of self-reported smoking behaviors and that verified from urine cotinine concentration testing were significantly different. The sensitivity of self-reported smoking behavior was 66.7% with a specificity of 97.6%. There was no significant association between second-hand smoking and urine cotinine concentrations. Questionnaire survey self-reporting methods could underestimate the smoking behavior of female volunteer soldiers and routine testing with biochemical verification is necessary.

The data on long-term trends and factors of tobacco retailers’ compliance in Taiwan are limited. The new regulations of the Tobacco Hazards Prevention Act were established in 2009. Now, the government is planning to raise the minimum legal age (MLA) for purchasing tobacco products from 18 to 20, so the results of this study will be an important reference to promote new regulations in the future. We carried out an observational mystery shopping study design and data were collected from 2009 to 2019. In total, 6320 undercover tests were conducted to investigate selling by tobacco retailers to persons aged less than 18 years by an impartial third party annually. Logistic regression was used to analyze the factors influencing compliance by adjusting test variables and independent variables. The compliance rate increased by 8.4% annually and was better among tests conducted during summer vacation (AOR = 1.324), chain convenience stores (AOR = 3.651), supermarkets or hypermarkets (AOR = 1.973), and verifications with age (AOR = 15.345). It is the first study to explore long-term and national tobacco retailers’ enforcement effects by an impartial third party in Asia. The findings suggest that local health agencies should enhance enforcement on those stores which were tested during non-summer holidays and weekends, betel nut stands, and grocery stores.
