Papers prepared by the National Institute on Aging for the White House Conference on Aging (WHCoA). Injury in late life: II. Prevention.

Contemporary, systematic approaches to injury prevention are presented as guides for considering needless death and disability of older people because of falls, burns, and vehicular crashes. Injury results from an unfavorable relationship between etiologic agent and host within a particular environment setting. Abnormal energy exchange is the agent.

"Alternative" controls in a case-control study of endometrial cancer and exogenous estrogen.

To address the issue of detection bias among endometrial cancer cases and controls, women admitted to the North Carolina Memorial Hospital for dilatation and curettage (D&C) during 1970-1976 were selected as one of three control groups in a study of endometrial cancer and exogenous estrogen. Study subjects included 256 cases, 316 D&C controls, 224 gynecology controls and 321 community controls. The D&C controls had a higher frequency of estrogen use than either of the other control groups or the cases.

The interactive effects of induced abortion, inter-pregnancy interval and contraceptive use on subsequent pregnancy outcome.

Prior induced abortion and outcome of the next pregnancy are investigated, allowing for two intervening and potentially confounding variables: 1) length of interval between the termination of the first pregnancy and the conception of the next (inter-pregnancy interval) and 2) the utilization of contraception during this interval. Results show that non-contracepting (susceptibility) intervals which immediately precede a subsequent pregnancy are significantly shorter following an induced abortion than those following a spontaneous abortion or delivery. A life table analysis of all susceptibility intervals confirmed this finding.

An evaluation of studies concerning reproduction after first trimester induced abortion.

This report gives an estimate of the United States population at risk of fertility complications after legally induced abortion. It also includes a review of the published literature concerning long-term effects of abortion, such as secondary infertility, ectopic pregnancy, and adverse pregnancy complications.

Low birth weight subsequent to induced abortion. A historical prospective study of 948 women in Skopje, Yugoslavia.

In the fall of 1972, interviews were conducted with 948 Yugoslavian women whose first pregnancies had been terminated by induced abortion (222) or delivery (726) during 1968-1969. Subjects were indentified from records of the Obstetrics and Gynecology Clinic of Skopje University, Macedonia. Subsequent pregnancies were studied to determine the relative effects of first-pregnancy abortion or delivery on incidences of adverse outcomes.
