Independent variables are the full set of variables whose influence on the outcome is studied. Covariates are the independent variables that are included not because they are of interest but because their influence on the outcome can be adjusted for, leaving a more precise understanding of how the single remaining independent variable influences the outcome. Confounding variables are variables that are associated with both independent variables and outcomes; so, the relationship identified between independent variables and outcomes may be due to the confounding variable rather than to the independent variable. Potential confounders should be identified, measured, and adjusted for in regression, just as other covariates are. Confounding by indication occurs when the presence of the independent variable is driven by the confounding variable. Confounding by indication is a special kind of confounding; a confounding variable is a special kind of covariate; and a covariate is a special kind of independent variable in regression analysis. These terms and concepts are explained with the help of examples.","PeriodicalId":507849,"journal":{"name":"Indian Journal of Psychological Medicine","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139845948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to assess the course and outcome of anorexia nervosa in adolescents who had presented to a tertiary care child and adolescent psychiatry center over a period of 10 years. The present study is a retrospective chart review of adolescents (up to the age of 18 years) with a diagnosis of anorexia nervosa, coded as F50.0 or F50.1 according to ICD 10, from 1st April 2009 to 31st March 2019. Data were extracted from the case records using standardized abstraction forms and evaluated using descriptive and nonparametric statistics. The average age at presentation and the average age at onset were 14.1 years and 13.1 years, respectively. The male-to-female ratio of the sample who got admitted was 1:9. The average duration of hospital stay was about 30 days. The duration of in-patient care and weight gain were positively correlated, with severe to extremely ill adolescents improving even in less than one month of in-patient care. Seventy per cent of the admitted adolescents followed up. The functional outcome as measured by a ‘return to school’ improved in 57.1% of the sample. The present study highlights the collaborative multidisciplinary and individualized treatment approach employed for adolescents diagnosed with anorexia nervosa within an inpatient mental health facility in India. Adolescents who presented with more severe illness at the initial assessment, such as an early onset of symptoms and a low BMI, experienced substantial weight gain that exhibited a positive correlation with the length of their stay in the inpatient facility.","PeriodicalId":507849,"journal":{"name":"Indian Journal of Psychological Medicine","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139806331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
