Multinomial Logistic Regression Analyses (multinomial + logistic_regression_analysis)
Selected AbstractsThe U.S. Destinations of Contemporary Mexican Immigrants1INTERNATIONAL MIGRATION REVIEW, Issue 4 2008Eileen Diaz McConnell Although U.S. Latinos continue to be concentrated in particular places, many have shifted to "new" locations around the country. This study employs data from the Mexican Migration Project (MMP107) to examine the relationship between individual-level characteristics and diverse U.S. destinations chosen by post-1965 Mexican immigrants. Multinomial logistic regression analyses confirm the importance of human capital, social networks, and temporal context in directing immigrants to particular U.S. sites. The findings also suggest that employing a typology of U.S. destinations is useful for understanding the spatial distributions of contemporary Mexican immigrants. [source] Potential for Alcohol and Prescription Drug Interactions in Older PeopleJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 11 2005Kristine E. Pringle PhD Objectives: To examine the patterns and prevalence of concomitant alcohol and alcohol-interactive (AI) drug use in older people. Design: Cross-sectional analysis of survey and prescription claims data. Setting: The Pennsylvania Pharmaceutical Assistance Contract for the Elderly (PA-PACE) program, a state-funded program providing prescription benefits to older people with low to moderate incomes. Participants: A total of 83,321 PA-PACE cardholders (age range 65,106) who were using any prescription medications at the time of survey completion. Measurements: All AI drugs were identified using a database of medication warning labels obtained from First DataBank. Prescription drug claims were used to characterize AI drug exposure according to therapeutic class of prescription drug use. A mail survey of PA-PACE cardholders was used to examine alcohol use, as well as sociodemographic and health factors associated with concomitant use of alcohol and AI drugs. Results: Seventy-seven percent of all prescription drug users were exposed to AI medications, with significant variation in exposure and concomitant alcohol use according to therapeutic class. Overall, 19% of AI drug users reported concomitant alcohol use, compared with 26% of non-AI drug users (P<.001). Multinomial logistic regression analyses showed that certain groups of older people, including younger older people, men, and those with higher educational levels, were at greater risk for concomitant exposure to alcohol and AI drugs. Conclusion: Many older people use alcohol in combination with AI prescription drugs. Clinicians should warn every patient who is prescribed an AI drug about alcohol,drug interactions, especially those at high risk for concomitant exposure. [source] Correlates of smoking among adolescents with asthmaJOURNAL OF CLINICAL NURSING, Issue 5-6 2010Su-Er Guo Aims and objective., This study examined the correlates of smoking among asthmatic adolescents to gain a better understanding of who is at particular risk. Background., Smoking is especially harmful to individuals with asthma. However, smoking is surprisingly prevalent among asthmatic individuals, with prevalence rates similar to or higher than those of the general adult or adolescent populations. Despite this notable finding, there has been little research about factors (i.e. biophysical, psychosocial and behavioural) influencing asthmatic adolescents' tobacco use patterns. Design., A Canadian provincial cross-sectional survey. Method., The study about adolescents' tobacco use and health status was conducted in secondary schools in 2004, 608 asthmatic adolescents participated. Demographic factors, biophysical (body mass index and physical health), psychosocial factors (parents' and peers' smoking, environmental tobacco smoke exposure and depression) and behavioural factors (marijuana use, alcohol use and exercise frequency) were explored. Multinomial logistic regression analyses were conducted to identify risk factors associated with tobacco use. Results and conclusions., Of the 608 asthmatic adolescents, 17·4% currently smoked and 12·0% formerly smoked. Girls, compared with boys, were more likely to smoke (OR: 3·34, 95% CI: 1·62,6·96) after adjusting for differences in the other demographic, biophysical, psychosocial and behavioural factors. Asthmatic girls who had relatively higher body mass index, were in the higher school grades, used marijuana or alcohol, had minor to severe depressive symptoms, had environmental tobacco smoke exposure in their homes and had friends who smoked or were currently more likely to smoke. The former smokers had similar risk factors including higher body mass index, environmental tobacco smoke exposure at home, friends who smoked and marijuana use. Relevance to clinical practice., Despite their health condition, asthmatic adolescents continue currently or formerly to smoke. Gender appropriate prevention and cessation interventions for asthmatic adolescents may need to address important psychosocial and environmental factors that increase the risk of these adolescents initiating and maintaining tobacco use. [source] No Influence of 5-HTTLPR Gene Polymorphism on Migraine Symptomatology, Comorbid Depression, and ChronificationHEADACHE, Issue 3 2010Thomas Wieser MD (Headache 2010;50:420-430) Background., The serotonergic system is thought to play an important role for mediating susceptibility to migraine and depression, which is frequently found comorbid in migraine. The functional polymorphism in the serotonin transporter gene linked polymorphic region (5-HTTLPR/SLC6A4) was previously associated with attack frequency and, thus, possibly with chronification. Objective., We hypothesized that patients with the "s" allele have higher attack frequency and, paralleling results in depression research, higher scores of depression. Methods., Genetic analysis of the SLC6A4 44 bp insertion/deletion polymorphism (5-HTTLPR) was performed in 293 patients with migraine with and without aura. Self-rating questionnaires were used for assessment of depression. Results., Multinomial logistic regression analysis found no evidence for association of the 5-HTTLPR polymorphism with either depression or migraine attack frequency. Conclusion., We were not able to demonstrate any influence of the serotonin transporter 5-HTTLPR polymorphism on migraine phenomenology (attack frequency or comorbid depression), thereby excluding this variant to be a common genetic denominator for chronic migraine and depression. [source] Pre- and postnatal influences on preschool mental health: a large-scale cohort studyTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 10 2008Monique Robinson Background:, Methodological challenges such as confounding have made the study of the early determinants of mental health morbidity problematic. This study aims to address these challenges in investigating antenatal, perinatal and postnatal risk factors for the development of mental health problems in pre-school children in a cohort of Western Australian children. Methods:, The Raine Study is a prospective cohort study of 2,868 live born children involving 2,979 pregnant women recruited at 18 weeks gestation. Children were followed up at age two and five years. The Child Behaviour Checklist (CBCL) was used to measure child mental health with clinical cut-points, including internalising (withdrawn/depressed) and externalising (aggressive/destructive) behaviours (n = 1707). Results:, Multinomial logistic regression analysis showed that the significant risk factors for behaviour problems at age two were the maternal experience of multiple stress events in pregnancy (OR = 1.20, 95% CI = 1.06, 1.37), smoking during pregnancy (OR = 1.30, 95% CI = 1.06, 1.59) and maternal ethnicity (OR = 3.34, 95% CI = 1.61, 6.96). At age five the experience of multiple stress events (OR = 1.17, 95% CI = 1.08, 1.27), cigarette smoking (OR = 1.19, 95% CI = 1.03, 1.37), male gender (OR = 1.43, 95% CI = 1.02, 2.00), breastfeeding for a shorter time (OR = .97, 95% CI = .94, .99) and multiple baby blues symptoms (OR = 1.08, 95% CI = 1.02, 1.14) were significant predictors of mental health problems. Conclusions:, Early childhood mental health is significantly affected by prenatal events in addition to the child's later environment. Interventions targeting adverse prenatal, perinatal and postnatal influences can be expected to improve mental health outcomes for children in the early years. [source] Demographic and socio-economic factors associated with dental health among older people in NSWAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2004Clare Ringland Objective: To investigate the association between oral health status and social, economic and demographic factors in community-dwelling older people in New South Wales (NSW). Methods: Binary and multinomial logistic regression analyses were used to examine the associations between measures of oral health status (edentulous/dentate, and the frequency of toothache or mouth or denture problems in the previous 12 months) and demographic and socio-economic factors using data from the NSW Older People's Health Survey 1999. Results: After adjusting for other factors, being edentulous was associated with being older, having no private dental insurance, being female, leaving school at less than 15 years of age, not being financially comfortable, not being a homeowner, living in a rural area, and being unable to travel alone. Among both dentate and edentulous people, increasing age and being able to travel independently were associated with decreased reporting of toothache, mouth or denture problems; while not being financially comfor table was associated with increased reporting of toothache or mouth or denture problems. The frequency of mouth or denture problems was not found to be independently associated with having private dental insurance nor with holding a health concession card. Conclusions: Among older people in NSW, oral health is associated with a range of demographic and socio-economic factors. The results suggest that better oral health among older people is associated with a capacity to pay out-of-pocket dental expenses rather than with private dental insurance or having access to public-funded dental care. [source] Socioeconomic indicators and prosthetic replacement of missing teeth in a working-age population,Results of the Study of Health in Pomerania (SHIP)COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 2 2009Torsten Mundt Abstract,,, Objectives:, To analyse the possible effects of the socioeconomic status (SES) on the prosthetic replacement of missing teeth in working-age people and to explore the role of potential confounders. Methods:, Cross-sectional data were collected from 2310 German adults aged 30,59 years. The relationship between each of the three SES indicators (education, income, and occupational status) and dental prostheses were examined by multinomial logistic regression analyses. For that, partially dentate participants with suboptimal and no replacement of missing teeth were compared with partially dentate participants having optimal replacement. Potential confounders (age, sex, dental status, social network and social support) were entered if their inclusion in the model led to ,10% change in the coefficient of interest. Results:, Social network and social support did not meet the criterion for confounding. In the maxilla, having no replacement was positively associated with lower categories for each of the three SES indicators [Odds ratios (OR) between 1.6 and 2.1; 95% confidence intervals (CI) between 1.1 and 3.4]. Low occupational status was the single predictor for suboptimal dental prostheses (OR = 3.2; 95% CI: 1.6,6.2). In the mandible, occupational status showed no association with the prosthetic status, whereas low educational level and low household income were determinants for having no replacement (OR = 1.9 and 1.9, 95% CI: 1.0,3.5 and 1.1,3.0, respectively). Low household income was the single determinant for suboptimal replacement of missing teeth (OR = 2.4, 95% CI = 1.1,5.2). Conclusion:, The findings may indicate the relevance of the financing of prosthodontic treatment. The strong association between various forms of upper dentures and occupational prestige can be seen as key contributing concept to how individuals, characteristics affect the outcome in prosthodontic care. [source] Institutional discharges and subsequent shelter use among unaccompanied adults in New York CityJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2010Stephen Metraux This study empirically examines the link between homelessness and discharges from other institutions. An administrative record match was undertaken to determine rates of discharge from institutional care for 9,247 unaccompanied adult shelter users in New York City. Cluster analysis and multinomial logistic regression analysis was then used to assess associations between different types of institutional discharges and the likelihood of persons subsequently experiencing extended shelter stays. Results show that 28% of the cohort was discharged from institutional care within the 90-day period preceding their initial shelter entry, with different types of institutional discharge associated with differences in subsequent patterns of shelter use. Based on these findings, transitions from institution to the community are potentially a key intervention point for reducing homelessness and shelter use. © 2009 Wiley Periodicals, Inc.
