Body weight and mortality among women.

BACKGROUND: The relation between body weight and overall mortality remains controversial despite considerable investigation. METHODS: We examined the association between body-mass index (defined as the weight in kilograms divided by the square of the height in meters) and both overall mortality and mortality from specific causes in a cohort of 115,195 U.S. women enrolled in the prospective Nurses' Health Study. These women were 30 to 55 years of age and free of known cardiovascular disease and cancer in 1976. During 16 years of follow-up, we documented 4726 deaths, of which 881 were from cardiovascular disease, 2586 from cancer, and 1259 from other causes. RESULTS: In analyses adjusted only for age, we observed a J-shaped relation between body-mass index and overall mortality. When women who had never smoked were examined separately, no increase in risk was observed among the leaner women, and a more direct relation between weight and mortality emerged (P for trend < 0.001). In multivariate analyses of women who had never smoked and had recently had stable weight, in which the first four years of follow-up were excluded, the relative risks of death from all causes for increasing categories of body-mass index were as follows: body-mass index < 19.0 (the reference category), relative risk = 1.0; 19.0 to 21.9, relative risk = 1.2; 22.0 to 24.9, relative risk = 1.2; 25.0 to 26.9, relative risk = 1.3; 27.0 to 28.9, relative risk = 1.6; 29.0 to 31.9, relative risk = 2.1; and > or = 32.0, relative risk = 2.2 (P for trend < 0.001). Among women with a body-mass index of 32.0 or higher who had never smoked, the relative risk of death from cardiovascular disease was 4.1 (95 percent confidence interval, 2.1 to 7.7), and that of death from cancer was 2.1 (95 percent confidence interval, 1.4 to 3.2), as compared with the risk among women with a body-mass index below 19.0. A weight gain of 10 kg (22 lb) or more since the age of 18 was associated with increased mortality in middle adulthood. CONCLUSIONS: Body weight and mortality from all causes were directly related among these middle-aged women. Lean women did not have excess mortality. The lowest mortality rate was observed among women who weighed at least 15 percent less than the U.S. average for women of similar age and among those whose weight had been stable since early adulthood.

Alcohol, height, and adiposity in relation to estrogen and prolactin levels in postmenopausal women.

BACKGROUND: Alcohol use, height, and postmenopausal adiposity have each been positively associated with postmenopausal breast cancer risk in most epidemiologic studies. The mechanism underlying these associations is unclear, although an effect of these factors on hormone levels has been hypothesized. Few previous studies have evaluated the relationship of either alcohol consumption or height with plasma hormone levels. A positive association between adiposity and plasma estrogen levels in postmenopausal women has been reported consistently. PURPOSE: Using archived frozen plasma samples and corresponding data from participants in the Nurses' Health Study, we determined plasma hormone levels and assessed these levels in relation to alcohol consumption, height, and adiposity among postmenopausal women. METHODS: Blood samples were collected from a subset of participants in the Nurses' Health Study in 1989 and 1990, then stored in liquid nitrogen. Hormone concentrations in 217 archived plasma samples (from healthy postmenopausal women) were analyzed in 1993. Spearman correlation coefficients were calculated to assess the linear association between alcohol consumption during the previous year (mean daily intake in grams per day ascertained from semiquantitative food-frequency questionnaires completed in 1990 or 1991), height, and adiposity (as measured by body mass index [BMI] in kg/m2, with weight reported at time of blood collection), and plasma hormone levels. Two-sided P values were also calculated. RESULTS: After controlling for age, height, smoking status, and BMI, alcohol consumption was positively associated with estrone sulfate concentrations (r = .17; P = .02); no statistically significant association was noted for the other plasma hormones measured. Mean plasma estrone sulfate levels were 159 pg/mL in women who reported no alcohol use versus 211 pg/mL in women consuming 30 g or more of alcohol per day. After adjusting for the other covariates, we observed a strong positive correlation between BMI and plasma estrogens (r ranging from .37 for estrone and estrone sulfate to .63 for bioavailable estradiol, with all P values < or = .01; prolactin was the only hormone unassociated with BMI, r = -.01). Height was unrelated to either plasma estrogens or prolactin. CONCLUSIONS: BMI and alcohol use were positively associated with postmenopausal plasma estrogen and estrone sulfate levels, respectively. IMPLICATIONS: The association of alcohol consumption and postmenopausal obesity with subsequent breast cancer risk might be mediated, at least in part, through an influence on postmenopausal plasma estrogen levels. Additional studies are needed to further quantify the relationship between alcohol consumption and plasma hormone levels and to elucidate the physiologic basis for this association.

Fish consumption and cardiovascular disease in the physicians' health study: a prospective study.

The authors examined the association between dietary intake of fish and omega 3 fatty acids from seafood and the risk of cardiovascular disease in a prospective cohort study of 21,185 US male physicians who are participants in the Physicians' Health Study. In 4 years of follow-up, there were 281 incident cases of total (fatal and nonfatal) myocardial infarction, 173 cases of stroke, and 121 cardiovascular deaths. There was no evidence for association between dietary intake of fish and any cardiovascular endpoint, including myocardial infarction, stroke, and cardiovascular death. The relative risks of total myocardial infarction, adjusted for age and randomized treatment assignment, for categories of fish intake were: 1.0 for < 1 meal/week (referent), 1.6 (95% confidence interval (Cl) 1.1-2.3) for 1 fish meal/week; 1.4 (95% Cl 1.0-2.0) for 2-4 fish meals/week; and 1.2 (95% Cl 0.6-2.2) for > or = 5 fish meals/week; chi 2 for trend = 0.9, p = 0.34. The relative risks were similar for omega 3 fatty acid intake and for specific types of fish, and did not change after adjustment for history of hypertension, hypercholesterolemia, diabetes mellitus, or angina pectoris, parental history of myocardial infarction before age 60 years, obesity, exercise, smoking, alcohol use, saturated fat intake, and vitamin supplement use. These data do not support the hypothesis that moderate fish consumption lowers the risk of cardiovascular disease.

The use of estrogens and progestins and the risk of breast cancer in postmenopausal women.

BACKGROUND: The effect of adding progestins to estrogen therapy on the risk of breast cancer in postmenopausal women is controversial. METHODS: To quantify the relation between the use of hormones and the risk of breast cancer in postmenopausal women, we extended our follow-up of the participants in the Nurses' Health Study to 1992. The women were asked to complete questionnaires every two years to update information on their menopausal status, use of estrogen and progestin preparations, and any diagnosis of breast cancer. During 725,550 person-years of follow-up, we documented 1935 cases of newly diagnosed invasive breast cancer. RESULTS: The risk of breast cancer was significantly increased among women who were currently using estrogen alone (relative risk, 1.32; 95 percent confidence interval, 1.14 to 1.54) or estrogen plus progestin (relative risk, 1.41; 95 percent confidence interval, 1.15 to 1.74), as compared with postmenopausal women who had never used hormones. Women currently taking hormones who had used such therapy for 5 to 9 years had an adjusted relative risk of breast cancer of 1.46 (95 percent confidence interval, 1.22 to 1.74), as did those currently using hormones who had done so for a total of 10 or more years (relative risk, 1.46; 95 percent confidence interval, 1.20 to 1.76). The increased risk of breast cancer associated with five or more years of postmenopausal hormone therapy was greater among older women (relative risk for women 60 to 64 years old, 1.71; 95 percent confidence interval, 1.34 to 2.18). The relative risk of death due to breast cancer was 1.45 (95 percent confidence interval, 1.01 to 2.09) among women who had taken estrogen for five or more years. CONCLUSIONS: The addition of progestins to estrogen therapy does not reduce the risk of breast cancer among postmenopausal women. The substantial increase in the risk of breast cancer among older women who take hormones suggests that the trade-offs between risks and benefits should be carefully assessed.

Alcohol consumption and mortality among women.

BACKGROUND: Studies in men suggest that light-to-moderate alcohol intake is associated with a reduction in overall mortality, due primarily to a reduced risk of coronary heart disease. Among women with similar levels of alcohol consumption, an increased risk of breast cancer has been noted that complicates the balance of risks and benefits. METHODS: We conducted a prospective study among 85,709 women, 34 to 59 years of age and without a history of myocardial infarction, angina, stroke, or cancer, who completed a dietary questionnaire in 1980. During the 12-year follow-up period, 2658 deaths were documented. RESULTS: The relative risks of death in drinkers as compared with nondrinkers were 0.83 (95 percent confidence interval, 0.74 to 0.93) for women who consumed 1.5 to 4.9 g of alcohol per day (one to three drinks per week), 0.88 (95 percent confidence interval, 0.80 to 0.98) for those who consumed 5.0 to 29.9 g per day, and 1.19 (95 percent confidence interval, 1.02 to 1.38) for those who consumed 30 g or more per day, after adjustment for other predictors of mortality. Light-to-moderate drinking (1.5 to 29.9 g per day) was associated with a decreased risk of death from cardiovascular disease; heavier drinking was associated with an increased risk of death from other causes, particularly breast cancer and cirrhosis. The benefit associated with light-to-moderate drinking was most apparent among women with risk factors for coronary heart disease and those 50 years of age or older. CONCLUSIONS: Among women, light-to-moderate alcohol consumption is associated with a reduced mortality rate, but this apparent survival benefit appears largely confined to women at greater risk for coronary heart disease.

Weight gain as a risk factor for clinical diabetes mellitus in women.

OBJECTIVE: To examine the relation between adult weight change and the risk for clinical diabetes mellitus among middle-aged women. DESIGN: Prospective cohort study with follow-up from 1976 to 1990. SETTING: 11 U.S. states. PARTICIPANTS: 114,281 female registered nurses aged 30 to 55 years who did not have diagnosed diabetes mellitus, coronary heart disease, stroke, or cancer in 1976. OUTCOME MEASURES: Non-insulin-dependent diabetes mellitus. RESULTS: 2204 cases of diabetes were diagnosed during 1.49 million person-years of follow-up. After adjustment for age, body mass index was the dominant predictor of risk for diabetes mellitus. Risk increased with greater body mass index, and even women with average weight (body mass index, 24.0 kg/m2) had an elevated risk. Compared with women with stable weight (those who gained or lost less than 5 kg between age 18 years and 1976) and after adjustment for age and body mass index at age 18 years, the relative risk for diabetes mellitus among women who had a weight gain of 5.0 to 7.9 kg was 1.9 (95% CI, 1.5 to 2.3). The corresponding relative risk for women who gained 8.0 to 10.9 kg was 2.7 (CI, 2.1 to 3.3). In contrast, women who lost more than 5.0 kg reduced their risk for diabetes mellitus by 50% or more. These results were independent of family history of diabetes. CONCLUSION: The excess risk for diabetes with even modest and typical adult weight gain is substantial. These findings support the importance of maintaining a constant body weight throughout adult life and suggest that the 1990 U.S. Department of Agriculture guidelines that allow a substantial weight gain after 35 years of age are misleading.

Weight, weight change, and coronary heart disease in women. Risk within the 'normal' weight range.

OBJECTIVE--To assess the validity of the 1990 US weight guidelines for women that support a substantial gain in weight at approximately 35 years of age and recommend a range of body mass index (BMI) (defined as weight in kilograms divided by the square of height in meters) from 21 to 27 kg/m2, in terms of coronary heart disease (CHD) risk in women. DESIGN--Prospective cohort study. SETTING--Female registered nurses in the United States. PARTICIPANTS--A total of 115,818 women aged 30 to 55 years in 1976 and without a history of previous CHD. MAIN OUTCOME MEASURE--Incidence of CHD defined as nonfatal myocardial infarction or fatal CHD. RESULTS--During 14 years of follow-up, 1292 cases of CHD were ascertained. After controlling for age, smoking, menopausal status, postmenopausal hormone use, and parental history of CHD and using as a reference women with a BMI of less than 21 kg/m2, relative risks (RRs) and 95% confidence intervals (CIs) for CHD were 1.19 (0.97 to 1.44) for a BMI of 21 to 22.9 kg/m2, 1.46 (1.20 to 1.77) for a BMI of 23 to 24.9 kg/m2, 2.06 (1.72 to 2.48) for a BMI of 25 to 28.9 kg/m2, and 3.56 (2.96 to 4.29) for a BMI of 29 kg/m2 or more. Women who gained weight from 18 years of age were compared with those with stable weight (+/- 5 kg) in analyses that controlled for the same variables as well as BMI at 18 years of age. The RRs and CIs were 1.25 (1.01 to 1.55) for a 5- to 7.9-kg gain, 1.64 (1.33 to 2.04) for an 8- to 10.9-kg gain, 1.92 (1.61 to 2.29) for an 11- to 19-kg gain, and 2.65 (2.17 to 3.22) for a gain of 20 kg or more. Among women with the BMI range of 18 to 25 kg/m2, weight gain after 18 years of age remained a strong predictor of CHD risk. CONCLUSIONS--Higher levels of body weight within the "normal" range, as well as modest weight gains after 18 years of age, appear to increase risks of CHD in middle-aged women. These data provide evidence that current US weight guidelines may be falsely reassuring to the large proportion of women older than 35 years who are within the current guidelines but have potentially avoidable risks of CHD.

Body mass index. An independent predictor of cataract.

OBJECTIVE: To examine whether body mass index is an independent predictor of cataract. (Body mass index is a standardized measure defined as weight in kilograms divided by the square of the height in meters.) DESIGN: Prospective cohort study, with 5 years of follow-up. PARTICIPANTS: A total of 17,764 US male physicians participating in the Physicians' Health Study, aged 40 to 84 years, who were free of cataract, myocardial infarction, stroke, and cancer at baseline and reported complete information about body mass index and other cataract risk factors. MAIN OUTCOME MEASURE: Incident cataract, defined as a self-report, confirmed by medical record review, first diagnosed after randomization, age-related in origin, and responsible for a decrease in best corrected visual acuity to 20/30 or worse. RESULTS: Incident cataract occurred during follow-up in 370 participants. In proportional hazards models that adjusted for potential confounding variables, body mass index had a strong, graded relationship with risk of cataract. Relative to those with body mass index less than 22, relative risks (95% confidence intervals) associated with body mass index of 22 to less than 25, 25 to less than 27.8, and 27.8 or more were 1.54 (1.04 to 2.27), 1.46 (0.98 to 2.20), and 2.10 (1.35 to 3.25), respectively. Relative to any given level of body mass index, a 2-unit higher level predicted a 12% increase in risk of cataract (95% confidence interval, 5% to 19%). Higher body mass index was especially strongly related to risk of posterior subcapsular and nuclear sclerotic cataracts and was also significantly related to risk of cataract extraction. CONCLUSIONS: In a prospective cohort study of apparently healthy men, higher body mass index, a potentially modifiable risk factor, was a determinant of cataract. The leanest men had the lowest rates, consistent with experimental evidence that restriction of energy intake slows development of cataract. Although precise mechanisms are unclear, the effect of body mass index on cataractogenesis is apparently independent of other risk factors, including age, smoking, and diagnosed diabetes.

Reproductive factors and family history of breast cancer in relation to plasma estrogen and prolactin levels in postmenopausal women in the Nurses' Health Study (United States).

Parity, age at first birth, age at menarche, and a family history of breast cancer have each been associated consistently with breast cancer risk. Whether this increase in risk is mediated, at least in part, through changes in endogenous hormone levels is unclear. We conducted a cross-sectional study of the relationships between these factors and plasma hormone levels in 216 healthy postmenopausal women in the Nurses' Health Study (United States). The hormones evaluated were estradiol, percent and total free estradiol, percent and total bioavailable estradiol, estrone, estrone sulfate, and prolactin. After controlling for age, body mass index (weight/height2), and alcohol use, we observed inverse associations between estrone sulfate and parity (r = -0.15, P = 0.03) and between percent bioavailable estradiol and age at first birth (r = -0.17, P = 0.02). Although women with a family history of breast cancer tended to have higher estrogen levels compared with women without such history, the differences were not statistically significant. Age at menarche was not related significantly to any of the hormones. These data provide some additional evidence that the inverse relationship observed between parity and breast cancer risk may be mediated, at least in part, through decreased estrogen levels. Our data do not support a substantial influence of either family history of breast cancer or age at menarche on postmenopausal estrogen or prolactin levels.

A prospective study of consumption of carotenoids in fruits and vegetables and decreased cardiovascular mortality in the elderly.

Recent evidence suggests that oxidative damage may be involved in atherogenesis, and thus dietary antioxidants, such as beta-carotene, may reduce the risks of cardiovascular disease (CVD). We examined the association between consumption of carotene-containing fruits and vegetables and CVD mortality among 1299 elderly Massachusetts residents who provided dietary information as a part of the Massachusetts Health Care Panel Study. During a mean follow-up of 4.75 years, there were 161 deaths attributable to CVD, 48 of which were due to myocardial infarction. For total CVD death and fatal myocardial infarction, risks were lower among those residents in the highest quartile for consumption of carotene-containing fruits and vegetables as compared with those in the lowest. For death due to CVD, the relative risk (RR) was 0.54 (95% confidence interval (CI), 0.34 to 0.86; P for trend across quartiles, 0.004). For myocardial infarction the RR was 0.25 (95% CI, 0.09 to 0.67; P for trend, 0.002). These observational data are compatible with the hypothesis that increased dietary intake of carotenoids decreases the risks of CVD mortality; however, confounding cannot be ruled out. This hypothesis requires rigorous evaluation in randomized trials of sufficient size to detect reliably whether carotenoids confer small-to-moderate but clinically important protection against CVD.

A secondary prevention trial of antioxidant vitamins and cardiovascular disease in women. Rationale, design, and methods. The WACS Research Group.

The evidence for a potential benefit of antioxidant vitamins in the prevention and therapy of atherosclerotic disease is derived from laboratory, clinical, and observational epidemiologic studies but remains inconclusive. Data from randomized clinical trials are sparse, particularly for women. Therefore, it is both timely and important to conduct large-scale primary and secondary prevention trials of antioxidants and cardiovascular disease (CVD). The Women's Antioxidant and Cardiovascular Study (WACS) is a randomized, double-blind, placebo-controlled secondary prevention trial of the balance of benefits and risks of antioxidant vitamins (vitamins E and C, and beta-carotene) among 8000 women with preexisting CVD. This secondary prevention trial will be conducted as a companion to the recently started Women's Health Study, a primary prevention trial of vitamin E and beta-carotene, as well as aspirin. In the WACS, US female health professionals aged 40 years and older with a history of myocardial infarction, angina pectoris, coronary revascularization, stroke, transient cerebral ischemia, carotid endarterectomy, or peripheral artery surgery will be randomly assigned, utilizing a 2 x 2 x 2 factorial design, to receive vitamin E, vitamin C, beta-carotene, and/or placebo. Cardiovascular end points include nonfatal myocardial infarction, nonfatal stroke, coronary revascularization procedures, and total CVD mortality. The present article describes the rationale, design, and methods of the trial.

Discrimination in absorption or transport of beta-carotene isomers after oral supplementation with either all-trans- or 9-cis-beta-carotene.

Human subjects (n = 24) were supplemented with 100 mg beta-carotene/d for 6 d, either as synthetic all-trans-beta-carotene or a natural beta-carotene preparation derived from the alga Dunaliella salina, which consists of a 50:50 mixture of all-trans- and 6-cis-beta-carotene. This loading dose was followed by a 23-d maintenance dose consisting of alternate-day supplementation with 50 mg all-trans-beta-carotene or either 66 or 100 mg of the natural 50:50 isomeric mixture. The loading dose resulted in significant increases in plasma concentrations of both isomers, with the all-trans-beta-carotene-supplemented group showing a 7.2- and 5.0-fold increase in the all-trans and 9-cis concentrations in plasma, respectively. The group receiving the 50:50 mixture showed a 4.0- and 3.7-fold increase in the all-trans and 9-cis concentrations in plasma, respectively, without any apparent dose-dependency. However, even with the 50:50 mixture, the 9-cis concentrations were only a small fraction of the total plasma beta-carotene. Results after an additional 23-d period of alternate-day supplementation were not significantly different from those described above for the 6-d supplementation. Increases in low-density-lipoprotein concentrations of total beta-carotene correlated strongly with the increases seen in plasma concentrations. Lipid-soluble antioxidants vitamin E and ubiquinol were unaffected by beta-carotene supplementation. However, the amount of lycopene in the low-density lipoprotein decreased during this supplementation period. A strong discrimination between these two geometric isomers of beta-carotene was demonstrated, although the tissue site of discrimination was not determined.

Antioxidant vitamin-cardiovascular disease hypothesis is still promising, but still unproven: the need for randomized trials.

The hypothesis that antioxidant vitamins might decrease the risk of cardiovascular disease (CVD) is a promising area of research. At present, however, it is far from certain whether antioxidant vitamins confer protection against CVD. Evidence for the antioxidant vitamin-cardiovascular disease hypothesis has accumulated from several lines of research. Laboratory research has identified biochemical properties of antioxidant vitamins that could explain their possible role in inhibiting and delaying coronary atherosclerosis. Epidemiologic studies have provided support for the hypothesis by showing that people who consume high amounts of antioxidant vitamins through diet or supplements, or those with high concentrations of these nutrients in their blood, tend to have lower risks of CVD. In the case of the former, however, laboratory findings may not have relevance to free-living humans. Observational epidemiologic studies cannot exclude the possibility that people who consume antioxidant-rich diets or who take vitamin supplements also share other lifestyle or dietary practices that actually account for their lower disease rates. Because of these uncertainties, the only way to determine reliably whether antioxidants play any role in reducing the risk of CVD is to conduct large-scale, randomized trials of these agents, in which adequate doses of antioxidant vitamins are tested for a sufficient duration to allow for any benefits to emerge. Several large-scale trials are now ongoing in both primary and secondary prevention. The results of these trials over the next several years should provide reliable evidence for this promising, but as yet unproven, hypothesis.

The epidemiology of varicella and its complications.

The automated records of over 250,000 members of a health maintenance organization were analyzed to assess the epidemiology of varicella and its complications between 1 July 1990 and 30 June 1992. All complications were verified by review of full-text medical records. The incidence rates of varicella in persons < 15 years of age were 20%-50% lower than published figures, probably reflecting underreporting. The rates in those > or = 15 years old, however, were greater than those reported for 1972-1978 (607 vs. 291/10(5) years, 15-19 years old; 175 vs. 33/10(5) years, > or = 20 years old). The rates of hospitalization for uncomplicated varicella, skin superinfections, and pneumonia in children were, respectively, 15, 11, and 4 times higher than previous estimates. Hospitalization rates for adults with pneumonia and uncomplicated varicella were > 5 times higher than prior figures. Thus, varicella in adults and varicella complications in general may be more frequent than previously estimated.

Childhood socioeconomic status and risk of cardiovascular disease in middle aged US women: a prospective study.

OBJECTIVE: To examine prospectively the relationship of childhood socioeconomic status and risk of cardiovascular disease in middle aged women. DESIGN: A prospective cohort of women with 14 years follow up data (1976-90). SUBJECTS: A total of 117,006 registered female nurses aged 30 to 55 years in 1976 and free of diagnosed coronary heart disease, stroke, and cancer at baseline. MAIN OUTCOME MEASURES: Incident fatal coronary heart disease, non-fatal myocardial infarction, and stroke (fatal and non-fatal). RESULTS: Low socioeconomic status in childhood was associated with a modestly increased risk of incident non-fatal myocardial infarction and total cardiovascular disease in adulthood. Compared with middle aged women from white collar childhood backgrounds, the age adjusted risk of total cardiovascular disease for women from blue collar backgrounds was 1.13 (95% CI 1.02, 1.24) and that of non-fatal myocardial infarction was 1.23 (95% CI 1.06, 1.42). No significant increase in risk was observed for stroke or fatal coronary heart disease. Adjustment for differences in family and personal past medical history, medication use, exercise, alcohol intake, diet, birth weight, being breastfed in infancy, and adult socioeconomic circumstance somewhat attenuated the increased risks observed for women from blue collar childhood socioeconomic backgrounds. In multivariate analysis, women whose fathers had been manual labourers had the highest relative risk of total coronary heart disease (RR = 1.53; 95% CI 1.09, 2.16) and non-fatal myocardial infarction (RR = 1.67; 95% CI 1.11, 2.53) when compared with women whose fathers had been employed in the professions. CONCLUSION: In this group lower childhood socioeconomic status was associated with a small but significant increase in the risk of total coronary heart disease as well as non-fatal myocardial infarction. For women from the most socioeconomically disadvantaged childhood backgrounds, the association is not explained by differences in a large number of cardiovascular risk factors, by differences in adult socioeconomic status, or by differences in indices of nutrition during gestation or infancy.

The validity of recalled weight among younger women.

METHOD: The authors compared recalled weight at age 18 and self-reported current height among 118 participants in the Nurses' Health Study II cohort, aged 25-42 years in 1989, with records from physical examinations conducted at college or nursing school entrance. RESULTS: The correlation between recalled and measured past weight was 0.87 and between reported current height and measured past height was 0.94. Mean body mass index (BMI) values were 21.6 kg/m2 for BMI calculated using recalled weight and 22.1 kg/m2 using weight from medical records; the correlation was 0.84. Participants slightly under-reported weight at age 18 (mean difference = 1.4 kg). CONCLUSION: The validity of recalled weight at 18 years of age and self-reported height as an estimate of height at age 18 appears to be high among women in this cohort.
