Risk factors for parkinson’s disease: The leisure world cohort study

Paganini-Hill, Annlia·2001·Neuroepidemiology

Abstract

We conducted a case-control study nested within a prospective cohort study of 13,979 residents of Leisure World Laguna Hills, a retirement community in southern California, for etiologic clues for Parkinson's disease (PD). Between 1981 (when first mailed a health survey) and 1998, we identified 395 PD cases from death certificates, hospital discharge diagnoses and a 1992 follow-up questionnaire. Six controls were individually matched on sex, birth date (+/-2 years), vital status and, if dead, death date (+/-1 year) to each case. Baseline characteristics of the 395 cases and 2,320 controls were analyzed as potential PD risk factors. The risk of PD was significantly reduced among smokers, hypertensives, coffee drinkers and alcohol consumers, and significantly increased among those with 3 or more children and with a high intake of total vitamin A and dietary vitamin C. The multivariate odds ratios (95% confidence intervals) were 0.42 (0.22-0.80) for current cigarette smokers of 1+ pack/day, 0.62 (0.48-0.80) for current users of hypertensive medication, 0.71 (0.52-0.95) for coffee drinkers of 2+ cups/day and 0.77 (0.58-1.03) for drinkers of 2+ alcoholic drinks/day. Risk increased with increasing number of children (1.25 for 1, 1.34 for 2 and 1.90 for 3+ children; p for trend = 0.0003). The increased risks among individuals in the highest third of total vitamin A intake and of dietary vitamin C intake were no longer statistically significant after adjusting for the other variables. These findings suggest several environmental factors that may be related to the development of PD and support a multifactorial etiology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
