A study was conducted on the effect of recall period on occupational injury rates among older workers as well as on the rate ratios of these injuries for nine risk factors. Data obtained from the Health and Retirement Study performed by the Institute for Social Research were evaluated for risk factors including age, sex, education, income, economic class, job classification, residence, depressive symptoms, and memory. From the over 12,000 respondents, 9,089 were chosen who where aged 51 to 61, and who were employed during the preceding year. Thirteen separate annualized incidence rates of occupational injury for the 4 week periods preceding the date of the interview were calculated. A simple linear model was found to provide the best fit for the calculated injury incidence rates. The model suggested a 36% increase in the adjusted injury incidence rate if a recall period of 4 weeks was used rather than 1 year. An average increase of 37.5% was seen in adjusted injury rates compared with unadjusted rates for the subgroups of workers defined by the nine risk factors. Rate ratios, however, were much less affected by adjustment for recall period and generally varied by less than 10%.
