Adjusted Logistic Regression (adjusted + logistic_regression)
Selected AbstractsMaternal employment and the initiation of breastfeedingACTA PAEDIATRICA, Issue 4 2001S Noble This study examines whether planning to be employed postpartum has an effect on initiation of breastfeeding. Data were collected from questionnaires completed by mothers who were subjects in the prospective, population-based, Avon Longitudinal Study of Pregnancy and Childhood. The mothers of 10 530 full-term singleton infants gave information during pregnancy on their postpartum employment plans and their initial infant feeding methods. Information was also given by 7642 of these mothers on the timing of their postpartum employment plans. Adjusted logistic regression was performed to identify associations between (a) "any" plans to work postpartum and the initiation of breastfeeding, and (b) the timing of the commencement of work postpartum, and the initiation of breastfeeding. A total of 8316 (79%) of the women initiated breastfeeding. The decision to breastfeed was not associated with "any" plans to work postpartum. However, women who planned to commence work prior to 6 wk postpartum were significantly less likely to initiate breastfeeding compared with those not intending to work postpartum. Older, more highly educated women, women who had or were planning to attend childbirth classes, women who were breastfed as infants, women who did not smoke and women who were giving birth to their first child were significantly more likely to initiate breastfeeding. Conclusion: Planning to return to employment prior to 6 wk postpartum reduces the likelihood of initiating breastfeeding. As increasing numbers of mothers are returning to work shortly after the birth of their child, this finding could have implications for maintaining the current level of breastfeeding. [source] Network financial support and conflict as predictors of depressive symptoms among a highly disadvantaged populationJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2007Amy R. Knowlton The study examined multiple dimensions of social support as predictors of depressive symptoms among a highly vulnerable population. Social network analysis was used to assess perceived and enacted dimensions of support (emotional, financial, instrumental), network conflict, closeness, and composition. Participants were 393 current and former injection drug users who were 72% , poverty level, 96% African American, 39% HIV seropositive. At baseline, 37% had high depression scores (CES-D , 16). Adjusted logistic regression indicated that for every additional network member providing financial support, the odds of probable depression 1 year later decreased by 23%, and for every additional conflictive network tie the odds of depression increased by 57%. Findings suggest the greater importance to this population's psychological well-being of received support specific to environmental demands, rather than support perceived potentially available. The findings suggest potential directions for intervention. © 2007 Wiley Periodicals, Inc. [source] Anemia and cognitive performance in hospitalized older patients: results from the GIFA studyINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 6 2006Valentina Zamboni Abstract Background Anemia represents a major risk factor for adverse health-related events in older persons. The aim of this study was to evaluate the association between hemoglobin levels/anemia and cognitive function in hospitalized older persons. Method Data are from the Gruppo Italiano di Farmacovigilanza nell'Anziano (GIFA) study. Hemoglobin levels (in g/dL) were measured upon admission to hospital; anemia was defined according to the WHO criteria. Cognitive performance was assessed by the Abbreviated Mental Test (AMT) on admission; an AMT score <7 defined cognitive impairment. Logistic regressions and analyses of covariance were performed to evaluate the relationship between cognitive status and hemoglobin levels/anemia. Results Mean age of the sample (n,=,13,301) was 72.0 years. Participants with cognitive impairment presented a higher prevalence of anemia (47%) compared to those without cognitive impairment (35%, p,<,0.001). Adjusted logistic regressions showed that hemoglobin levels/anemia were significantly associated with cognitive impairment (OR,=,0.96, 95%CI,=,0.94,0.99, p,=,0.004, and OR,=,1.32, 95%CI,=,1.18,1.48, p,<,0.001, respectively). Patients with anemia and cognitive impairment at the hospital admission presented a higher number of impaired Activities of Daily Living compared to those with only one or none of the studied conditions (p for trend,<,0.001). Conclusion Low hemoglobin levels and anemia are independently associated with cognitive performance in older persons admitted to acute care units. Copyright © 2006 John Wiley & Sons, Ltd. [source] Association between interleukin-6 promoter haplotypes and aggressive periodontitisJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 3 2008Luigi Nibali Abstract Background: Interleukin-6 (IL-6) polymorphisms have been shown to affect IL-6 promoter activity. This study investigated the possible role of IL-6 genetic polymorphisms and haplotypes in the predisposition to aggressive periodontitis (AgP). Material and Methods: A case,control association study on 224 AgP patients and 231 healthy controls was performed in order to detect differences in genotype distributions of five single nucleotide polymorphisms (SNPs) located in the promoter region of the IL-6 gene. Results: The IL-6 ,1363 polymorphism was associated with a diagnosis of AgP in subjects of all ethnicities (p=0.006, adjusted logistic regression). The ,1480 SNP was associated with LAgP in subjects of all ethnicities (p=0.003). The ,1480 and ,6106 polymorphisms were associated with Localized AgP in Caucasians (n=24) (p=0.007 and 0.010, respectively). Haplotypes determined by the ,1363 and ,1480 polymorphisms were also associated with LAgP (p=0.001) in Caucasians. Conclusions: This study supports the hypothesis of a link between IL-6 genetic factors and AgP and highlights the importance of two IL-6 polymorphisms (,1363 and ,1480) in modulating disease phenotype and susceptibility.
