Abstract:Machines have difficulty when using people’s names to link medical and other records pertaining to the same individuals because of nicknames, ethnic synonyms, truncations, misspellings and typographical errors. Present algorithms used to compute the discriminating powers (or ODDS) associated with partial agreements of names are based, inappropriately, on the degrees of outward similarity alone. They are particularly ineffective in dealing with names that look alike but are unrelated, and with related names that have little apparent similarity. A fundamentally different rationale is, therefore, proposed which, like the human mind, assesses the relatedness of two alternative forms of a name in terms of how often they are used, interchangeably in practice. This must be taken into account if the associated discriminating powers (ODDS) are to be correctly computed. A way of implementing this more precise approach is described and illustrated, using the given names on linked records from an earlier epidemiological study. This first study of two describes the logical basis for record linkage, a second one the empirical test.

SynopsisOne thousand and ten unselected London state schoolgirls were screened by questionnaire to identify an ‘at risk’ cohort displaying abnormal eating attitudes and two control cohorts, one with probable general psychiatric morbidity, one without. Members of all cohorts were assessed at interview for the presence of eating disorder and for putative risk factors implicated in the development of anorexia nervosa. A prevalence rate of 0·99 % was detected for clinical eating disorder and 1·78 % for the partial syndrome of eating disorder. Factors specifically associated with abnormal eating attitudes were identified, in particular, current or past overweight, history of amenorrhoea and perceived stress in school and social life. Some commonly accepted risk factors for eating disorders were discovered to be associations with general psychiatric morbidity. These were perceived parental pressure to eat more, taking exercise to lose weight, perceived stress at home and reporting a family history of anxiety or depression. Other well reported putative risk factors for eating disorder, including social class, birth order, age at menarche, obsessional personality and weight related career choice were not associated specifically with abnormal eating attitudes in schoolgirls. These findings represent cross-sectional data at entry into a prospective epidemiological study.
