RESUMO

Even with antiretroviral therapy, children born to HIV-infected (HI) mothers are at a higher risk of early-life infections and morbidities including dental disease. The increased risk of dental caries in HI children suggest immune-mediated changes in oral bacterial communities, however, the impact of perinatal HIV exposure on the oral microbiota remains unclear. We hypothesized that the oral microbiota of HI and perinatally HIV-exposed-but-uninfected (HEU) children will significantly differ from HIV-unexposed-and-uninfected (HUU) children. Saliva samples from 286 child-participants in Nigeria, aged ≤ 6 years, were analyzed using 16S rRNA gene sequencing. Perinatal HIV infection was significantly associated with community composition (HI vs. HUU-p = 0.04; HEU vs. HUU-p = 0.11) however, immune status had stronger impacts on bacterial profiles (p < 0.001). We observed age-stratified associations of perinatal HIV exposure on community composition, with HEU children differing from HUU children in early life but HEU children becoming more similar to HUU children with age. Our findings suggest that, regardless of age, HIV infection or exposure, low CD4 levels persistently alter the oral microbiota during this critical developmental period. Data also indicates that, while HIV infection clearly shapes the developing infant oral microbiome, the effect of perinatal exposure (without infection) appears transient.

RESUMO

OBJECTIVE: To examine the efficacy and safety of Huo-Luo-Xiao-Ling (HLXL)-Dan, a Traditional Chinese Medicine (TCM), in patients with knee osteoarthritis (OA). DESIGN: A multi-site, randomized, double-blind, placebo-controlled phase II dose-escalation clinical trial was conducted. Eligible patients who fulfilled American College of Rheumatology criteria were randomized to receive either HLXL or placebo. Clinical assessments included measurement of knee pain and function with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), patient global assessment (PGA), and knee pain scores every 2 weeks. A Data and Safety Monitoring Board (DSMB) was established to review the data for ensuring the quality of the trial. RESULTS: In the first stage, 28 participants were randomized to receive either low-dose HLXL-Dan (2400 mg/day) or placebo for 6 weeks. The results showed no statistical difference between the two groups. The study was then re-designed following the recommendation of DSMB. Ninety-two patients were enrolled in the second stage and were randomized to receive either high-dose HLXL-Dan (4000 mg/day for week 1-2, and 5600 mg/day for week 3-8) or placebo for 8 weeks. All outcome assessments showed significant improvements for both groups after 8 weeks but no significant between-group differences. The change (mean ± SD) of WOMAC pain and WOMAC function scores of HLXL and placebo group after 8 weeks were -1.2 ± 1.7 vs -1.4 ± 1.5, and -1.1 ± 1.6 vs -1.3 ± 1.5 respectively. No serious adverse events were reported. CONCLUSION: Although safe to use, an 8-week treatment of HLXL-Dan was not superior to placebo for reduction in pain or functional improvement in patients with knee OA. CLINICAL TRIAL REGISTRATION NUMBER: Clinicaltrials.gov (NCT00755326).

RESUMO

Systemic autoimmune rheumatic diseases (SARDs) are chronic inflammatory and immuno-modulatory conditions that have been suggested to affect cancer risk. Using the Surveillance, Epidemiology and End Results-Medicare-linked database, women aged 67-99 years and diagnosed with incident breast cancer in 1993-2002 (n=84 778) were compared with an equal number of age-matched cancer-free female controls. Diagnoses of SARDs, including rheumatoid arthritis (RA, n=5238), systemic lupus erythematosus (SLE, n=340), Sjogren's syndrome (n=374), systemic sclerosis (n=128), and dermatomyositis (n=31), were determined from claim files for individuals from age 65 years to 1 year before selection. Associations of SARD diagnoses with breast cancer, overall and by oestrogen receptor (ER) expression, were assessed using odds ratio (OR) estimates from multivariable logistic regression models. The women diagnosed with RA were less likely to develop breast cancer (OR=0.87, 95% confidence interval (CI)=0.82-0.93). The risk reduction did not differ by tumour ER-status (OR=0.83, 95% CI=0.78-0.89 for ER-positive vs OR=0.91, 95% CI=0.81-1.04 for ER-negative, P for heterogeneity=0.14). The breast cancer risk was not associated with any of the other SARDs, except for a risk reduction of ER-negative cases (OR=0.49, 95% CI=0.26-0.93) among women with SLE. These findings suggest that systemic inflammation may affect breast epithelial neoplasia.

RESUMO

BACKGROUND: Abstracts of presentations at scientific meetings are usually available only in conference proceedings. If subsequent full publication of abstract results is based on the magnitude or direction of study results, publication bias may result. Publication bias, in turn, creates problems for those conducting systematic reviews or relying on the published literature for evidence. OBJECTIVES: To determine the rate at which abstract results are subsequently published in full, and the time between meeting presentation and full publication. To assess the association between study characteristics and full publication. SEARCH STRATEGY: We searched MEDLINE, EMBASE, The Cochrane Library, Science Citation Index, reference lists, and author files. Date of most recent search: June 2003. SELECTION CRITERIA: We included all reports that examined the subsequent full publication rate of biomedical results initially presented as abstracts or in summary form. Follow-up of abstracts had to be at least two years. DATA COLLECTION AND ANALYSIS: Two reviewers extracted data. We calculated the weighted mean full publication rate and time to full publication. Dichotomous variables were analyzed using relative risk and random effects models. We assessed time to publication using Kaplan-Meier survival analyses. MAIN RESULTS: Combining data from 79 reports (29,729 abstracts) resulted in a weighted mean full publication rate of 44.5% (95% confidence interval (CI) 43.9 to 45.1). Survival analyses resulted in an estimated publication rate at 9 years of 52.6% for all studies, 63.1% for randomized or controlled clinical trials, and 49.3% for other types of study designs.'Positive' results defined as any 'significant' result showed an association with full publication (RR = 1.30; CI 1.14 to 1.47), as did 'positive' results defined as a result favoring the experimental treatment (RR =1.17; CI 1.02 to 1.35), and 'positive' results emanating from randomized or controlled clinical trials (RR = 1.18, CI 1.07 to 1.30). Other factors associated with full publication include oral presentation (RR = 1.28; CI 1.09 to 1.49); acceptance for meeting presentation (RR = 1.78; CI 1.50 to 2.12); randomized trial study design (RR = 1.24; CI 1.14 to 1.36); and basic research (RR = 0.79; CI 0.70 to 0.89). Higher quality of abstracts describing randomized or controlled clinical trials was also associated with full publication (RR = 1.30, CI 1.00 to 1.71). AUTHORS' CONCLUSIONS: Only 63% of results from abstracts describing randomized or controlled clinical trials are published in full. 'Positive' results were more frequently published than not 'positive' results.

RESUMO

OBJECTIVE: Previous studies indicate that obesity is associated with a higher risk of experiencing hot flushes in mid-life women. The reasons for this association are unknown, although altered hormone levels have been associated with both hot flushes and obesity. Thus, this current study tested the hypothesis that obesity is associated with hot flushes in mid-life women through a mechanism involving levels of total and free androgen, free estrogen, progesterone, and sex hormone binding globulin (SHBG). METHODS: Women aged 45-54 years were recruited from Baltimore and its surrounding counties. Each participant (n=628) was weighed, measured, completed a questionnaire, and provided a blood sample that was used to measure estradiol, estrone, testosterone, androstenedione, dehydroepiandrosterone sulfate, progesterone, and SHBG. RESULTS: Obese mid-life women (body mass index (BMI)>or=30.0 kg/m2) had significantly higher testosterone, and lower estradiol, estrone, progesterone, and SHBG levels than normal-weight mid-life women (BMI

RESUMO

OBJECTIVES: The present study was conducted to assess the associations between a woman's passionate love for her partner and sexual satisfaction and demographic factors, health and life-style characteristics, menopausal status, and menopausal symptoms. METHODS: A cross-sectional study was conducted among women (40-60 years) residing in Maryland (n = 846). chi(2)-tests were performed to evaluate the associations between each of the outcome variables (sexual satisfaction and passionate love for the partner) and predictor/independent variables. Logistic regression analysis was performed to determine whether significant associations from chi(2) analyses remained significant after adjustment for confounders. RESULTS: Older age (adjusted odds ratio (OR) 1.04; 95% confidence interval (CI) 1.01, 1.07), higher education (OR 1.47; 95% CI 1.09, 1.99), and alcohol intake (OR 1.42; 95% CI 1.03, 1.95) were associated with low passion for the partner. Older age was also a significant predictor of low sexual satisfaction (OR 1.04; 95% CI 1.01, 1.07). Women experiencing vaginal dryness had higher odds of low passion for partner (OR 1.67; 95% CI 1.21, 1.31) and low sexual satisfaction (OR 1.58; 95% CI 1.14, 2.20) than women not experiencing vaginal dryness. CONCLUSIONS: Older age, higher education, alcohol intake, and vaginal dryness are significantly associated with lower levels of passionate love for the partner, while older age and vaginal dryness are significantly associated with lower levels of sexual satisfaction in midlife women.

RESUMO

Media coverage of scientific research plays a major role in shaping public opinion and influencing medical practice. When an association is controversial, such as with hormone replacement therapy (HRT) and breast cancer, it is important that a balanced picture of the scientific literature be reported. The objective of this study was to assess whether scientific publications that do and do not support an HRT/breast cancer association were cited in the media in proportions similar to those with which they appear in the scientific literature. Scientific publications reporting on the HRT/breast cancer association published from January 1, 1995, to June 30, 2000, were identified through a systematic Medline search. Media reports from newspapers, magazines, television, and radio that reported on HRT and breast cancer were retrieved from an online database. Investigators independently recorded characteristics of the scientific publications and media reports. A total of 32 scientific publications were identified: 20 (62.5%) concluded there was an increased risk of breast cancer associated with HRT (positive publications), and 12 (37.5%) concluded there was no evidence for an association (null publications). Nearly half (47%) of the scientific publications were not cited by the media. There were 203 media citations of scientific publications: 82% were of positive publications and 18% were of null publications, representing a significant excess of citations of positive publications (p < 0.01). Media coverage of this controversial issue is based on a limited sample of the scientific publications. Moreover, the excess of media citations for positive scientific publications suggests a bias against null scientific publications.

RESUMO

Coding region frameshift mutation caused by microsatellite instability (MSI) is one mechanism contributing to tumorigenesis in cancers with MSI in high frequency. Mutation of TGFBR2 is one example of this process. To identify additional examples, a large-scale genomic screen of coding region microsatellites was conducted. 1115 coding homopolymeric loci with six or more nucleotides were identified in an online genetic database. Mutational screening was performed at 152 of these loci in 46 colorectal tumors with MSI in high frequency. Nine loci were mutated in > or =20% of tumors, 10 loci in 10-20%, 24 loci in 5-10%, 43 loci in <5%, and 66 loci were not mutated in any tumors. The most frequently mutated novel loci were the activin type II receptor gene (58.1%), SEC63 (48.8%), AIM 2 (47.6%), a gene encoding a subunit of the NADH-ubiquinone oxidoreductase complex (27.9%), a homologue of mouse cordon-bleu (23.8%), and EBP1/PA2G4 (20.9%). This genome-wide approach identifies coding region MSI in genes or pathways not implicated previously in colorectal tumorigenesis, which may merit functional study or other additional analysis.

RESUMO

BACKGROUND: Non-high-density lipoprotein cholesterol (non-HDL-C) contains all known and potential atherogenic lipid particles. Therefore, non-HDL-C level may be as good a potential predictor of risk for cardiovascular disease (CVD) as low-density lipoprotein cholesterol (LDL-C). OBJECTIVES: To determine whether non-HDL-C level could be useful in predicting CVD mortality and to compare the predictive value of non-HDL-C and LDL-C levels. METHODS: Data are from the Lipid Research Clinics Program Follow-up Study, a mortality study with baseline data gathered from 1972 through 1976, and mortality ascertained through 1995. A total of 2406 men and 2056 women aged 40 to 64 years at entry were observed for an average of 19 years, with CVD death as the main outcome measure. RESULTS: A total of 234 CVD deaths in men and 113 CVD deaths in women occurred during follow-up. Levels of HDL-C and non-HDL-C at baseline were significant and strong predictors of CVD death in both sexes. In contrast, LDL-C level was a somewhat weaker predictor of CVD death in both. Differences of 0.78 mmol/L (30 mg/dL) in non-HDL-C and LDL-C levels corresponded to increases in CVD risk of 19% and 15%, respectively, in men. In women, differences of 0.78 mmol/L (30 mg/dL) in non-HDL-C and LDL-C levels corresponded to increases in CVD risk of 11% and 8%, respectively. CONCLUSIONS: Non-HDL-C level is a somewhat better predictor of CVD mortality than LDL-C level. Screening for non-HDL-C level may be useful for CVD risk assessment.

RESUMO

OBJECTIVE: Recent studies suggest that ovarian volume and antral follicle numbers may be sensitive, specific, and early indicators of menopausal status. The accuracy of these markers, however, has not been compared directly to more traditional markers [age and follicle-stimulating hormone (FSH) levels]. Thus, the purpose of this study was to test whether ovarian volume and antral follicle counts are more sensitive and specific markers of menopausal status than age or FSH levels. DESIGN: Premenopausal (n = 34) and postmenopausal (n = 25) women between 40 and 54 years old received a transvaginal ultrasound for determination of ovarian volume and antral follicle numbers, provided blood for measurement of FSH levels, and completed a questionnaire. FSH levels, age, ovarian volume, and antral follicle numbers were compared using t tests. Receiver operating characteristic curves were generated to evaluate the sensitivity and specificity of each marker. RESULTS: Postmenopausal women had significantly higher FSH levels (p < or = 0.0001), smaller ovarian volumes (p < or = 0.002), and fewer antral follicles (p < or = 0.002) than premenopausal women. Ovarian volume and antral follicle numbers had similar sensitivity (27.3-100%) and specificity (3.4-92.9%) in indicating postmenopausal status as FSH levels and age. CONCLUSION: These data suggest that ovarian volume and antral follicle numbers may be useful indicators of menopausal status.

RESUMO

OBJECTIVES: We sought to measure the characteristics of a quantitative human papillomavirus deoxyribonucleic acid assay and repeated cervical cytologic examination in screening for cervical intraepithelial neoplasia among human immunodeficiency virus-infected women. STUDY DESIGN: Human immunodeficiency virus-infected women with screening CD4+ lymphocyte counts of < or = 500 cells/mm3 (n = 103) were examined by quantitative human papillomavirus deoxyribonucleic acid assay and serial cervical cytologic examination and by colposcopy with biopsy and endocervical curettage during the course of 1 year. RESULTS: Quantitative measures of total human papillomavirus deoxyribonucleic acid and high-risk human papillomavirus deoxyribonucleic acid were strongly associated with any cervical intraepithelial neoplasia (P = .005) and high-grade cervical intraepithelial neoplasia (P = .0006), but they improved the sensitivity and negative predictive value of baseline screening only slightly when combined with cervical cytologic examination. Incident cervical intraepithelial neoplasia occurred frequently (20%) during 1 year of follow-up and was more common among human papillomavirus-infected women. Repeated cytologic examination identified 60% of women with new cervical intraepithelial neoplasia. CONCLUSION: Human immunodeficiency virus-infected women with at least mild immunosuppression have a high incidence of cervical intraepithelial neoplasia, which warrants close follow-up. Those with high baseline human papillomavirus deoxyribonucleic acid levels may be at the highest risk for incident cervical intraepithelial neoplasia.

RESUMO

OBJECTIVE: The objectives of this study were to measure patient satisfaction with the results of hysterectomy and to determine factors associated with dissatisfaction. STUDY DESIGN: A total of 1299 women who underwent hysterectomy at 28 hospitals in Maryland were interviewed before and at 3, 6, 12, 18, and 24 months after the operation. RESULTS: At 12 and 24 months after the hysterectomy 95.8% and 96.0%, respectively, reported that the hysterectomy had completely or mostly resolved the problems or symptoms they had before surgery; 93.3% and 93.7%, respectively, reported that the results were better than or about what they expected; 85.3% and 81. 6%, respectively, reported that their health was better than before the hysterectomy; and 87.9% and 93.1%, respectively, reported being totally recovered. The factor most strongly and consistently associated with patient reports of negative outcomes was readmission because of a postdischarge complication. CONCLUSION: Postdischarge complication necessitating readmission plays an important role in patient dissatisfaction with the results of hysterectomy.

RESUMO

The Maryland Women, Infants and Children (WIC) 5-A-Day Promotion Program examined the effect of a multifaceted nutrition intervention on changing the fruit and vegetable consumption of low-income women in the WIC program in Maryland. The sample consisted of 3,122 participants (1,443 intervention and 1,679 control) with a mean age of 27.2. Fifty-six percent were Black/African American. This article focuses on the effect of the intervention on the stages of change of the participants. Intervention participants showed significantly greater positive movement through the stages than control participants. Stages of change were measured for two specific target behaviors: eating five servings of fruits and vegetables a day and eating more servings of fruit and vegetables a day. Results demonstrated significant differences in the stage status of intervention and control women and in movement through the stages. The effectiveness of the intervention across groups depended on which staging measure was used.

RESUMO

BACKGROUND: Tamoxifen-treated breast carcinoma survivors are at elevated risk of endometrial carcinoma. Whether to recommend annual surveillance for uterine abnormalities in this population is currently under debate. METHODS: This study was a cross-sectional, community-based investigation of tamoxifen use and the frequency of surveillance for endometrial carcinomas in 541 women with breast carcinoma. Study participants whose breast carcinoma was diagnosed in 1994 were interviewed in 1998. Data were collected from a telephone interview and from a cancer registry record. Tests for uterine abnormalities, based on participant reports of endometrial biopsy and transvaginal ultrasound, were categorized according to frequency. Testing for uterine abnormalities was defined as irregular if women reported tests once every 3 years, on average, and as regular, if they reported annual tests. RESULTS: Forty-nine percent of respondents were current tamoxifen users, 12% were former tamoxifen users, and 39% reported never taking tamoxifen. Of respondents with a uterus (n = 385), 19% reported irregular and 30% regular testing for uterine abnormalities after their breast carcinoma diagnosis. Respondents more frequently reported transvaginal ultrasound (37%) than endometrial biopsy (29%). Women 65 years of age and older were significantly less likely to report regular surveillance for uterine abnormalities (16%) than those younger than 65 years (35%). Current tamoxifen users more frequently reported regular surveillance (43%) than either former (35%) or never tamoxifen users (15%). Multivariable analyses showed tamoxifen users were more likely to have regular (odds ratio [OR], 9.8; 95% confidence interval [CI], 4.4-21.8) or to have irregular testing for uterine abnormalities (OR, 3.9; 95% CI, 1.9-8.1) compared with women who never used tamoxifen, after adjustment for age, number of recent gynecologic visits, and gynecologic symptoms. CONCLUSIONS: The results of the current study indicate that half of the breast carcinoma survivors in this population were tested for uterine abnormalities. Although at increased risk, 38% of tamoxifen users never had a test. Clear guidelines need to be established for the type and frequency of testing for uterine abnormalities among tamoxifen-treated breast carcinoma patients.

RESUMO

OBJECTIVE: We sought to evaluate the use of the Breast Imaging Reporting and Data System (BI-RADS) standardized mammography lexicon among and within observers and to distinguish variability in feature analysis from variability in lesion management. MATERIALS AND METHODS: Five experienced mammographers, not specifically trained in BI-RADS, used the lexicon to describe and assess 103 screening mammograms, including 30 (29%) showing cancer, and a subset of 86 mammograms with diagnostic evaluation, including 23 (27%) showing cancer. A subset of 13 screening mammograms (two with malignant findings, 11 with diagnostic evaluation) were rereviewed by each observer 2 months later. Kappa statistics were calculated as measures of agreement beyond chance. RESULTS: After diagnostic evaluation, the interobserver kappa values for describing features were as follows: breast density, 0.43; lesion type, 0.75; mass borders, 0.40; special cases, 0.56; mass density, 0.40; mass shape, 0.28; microcalcification morphology, 0.36; and microcalcification distribution, 0.47. Lesion management was highly variable, with a kappa value for final assessment of 0.37. When we grouped assessments recommending immediate additional evaluation and biopsy (BI-RADS categories 0, 4, and 5 combined) versus follow-up (categories 1, 2, and 3 combined), five observers agreed on management for only 47 (55%) of 86 lesions. Intraobserver agreement on management (additional evaluation or biopsy versus follow-up) was seen in 47 (85%) of 55 interpretations, with a kappa value of 0.35-1.0 (mean, 0.60) for final assessment. CONCLUSION: Inter- and intraobserver variability in mammographic interpretation is substantial for both feature analysis and management. Continued development of methods to improve standardization in mammographic interpretation is needed.

RESUMO

Using a crossover design, the authors conducted a 6-month intervention program aimed at increasing fruit and vegetable consumption among women served by the Women, Infants, and Children program in Baltimore City and six Maryland counties. The theoretical framework for the interventions was the Transtheoretical Model of Change. At 2 months postintervention, mean daily consumption had increased significantly more in intervention participants than in control participants. Extensive process evaluation data were collected to assess the quantity and quality of program services delivered. These included participant nutrition session evaluation forms and attendance logs, focus groups of attenders and nonattenders of sessions, information about peer educators, and postintervention surveys. Many lessons were learned about program delivery, factors affecting attendance, and the obstacles to dietary change. Strategies to increase participants' consumption of fruits and vegetables were modified based on these lessons and the process evaluations.

RESUMO

OBJECTIVE: To measure the effectiveness of hysterectomy in relieving adverse symptoms and to identify factors associated with lack of symptom relief. METHODS: In a 2-year prospective study, data were collected before and at 3, 6, 12, 18, and 24 months after hysterectomy in 1,299 women who had hysterectomies for benign conditions at 28 hospitals across Maryland. Effectiveness was measured in terms of relief of symptoms such as problematic vaginal bleeding, pelvic pain, and urinary incontinence. Psychologic function and quality of life before and after surgery also were assessed. RESULTS: Symptom severity, depression, and anxiety levels decreased significantly after hysterectomy and quality of life improved, particularly in the area of social function. However, 8% of women had at least as many symptoms at problematic-severe levels 1 and 2 years after hysterectomy as before. In multiple logistic regression, several presurgical patient characteristics predicted lack of symptom relief, including therapy for emotional or psychologic problems, depression, and household income of $35,000 or less. Bilateral oophorectomy predicted lack of symptom relief at 24 months but not at 12 months after hysterectomy. CONCLUSION: Significant improvements were seen after hysterectomy for all three aspects of health status (symptoms, psychologic function, and quality of life), which persisted or continued to improve throughout the 2 years of follow-up. However, hysterectomy did not relieve symptoms for some women, particularly those who had low incomes or were in therapy at the time of hysterectomy.

RESUMO

OBJECTIVE: The purposes of this study were to (1) examine whether ovarian volume differs by age and menopausal status in healthy women; (2) evaluate whether ovarian volume could be a sensitive and specific predictor of menopausal status; and (3) assess whether ovarian volume is affected by cigarette smoke, oral contraceptives (OCs), and hormone replacement therapy (HRT). DESIGN: Each participant (527 women) completed an extensive in-home interview that assessed age, menopausal status, smoking history, OC use, and HRT use. Each participant also received a transvaginal ultrasound that measured ovarian volume. Geometric means for ovarian volume were compared between premenopausal and postmenopausal women using t tests. Tests for trends were conducted using linear regression analyses. RESULTS: Ovarian volume declined with age (p < or = 0.0001) and also differed by menopausal status; postmenopausal women had smaller ovarian volumes than premenopausal women of the same age (p < or = 0.0001). Ovarian volume was not associated with smoking history or HRT use. However, it was significantly smaller in current users of OCs compared with past users of or those who never used OCs (p < or = 0.0001). Ovarian volume was a sensitive and specific predictor of postmenopausal status. CONCLUSIONS: The data suggest that age, menopausal status, and OC use may be determinants of ovarian volume. They also suggest that ovarian volume may be useful for predicting menopausal status in women.

RESUMO

This study sought to examine: (a) the relative effects of baseline demographic and psychosocial factors and an intensive nutritional intervention on changes in fruit and vegetable consumption in low-income, ethnically diverse women served by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program in Maryland; (b) whether this intervention, designed to modify psychosocial factors associated with fruit and vegetable consumption, was successful in changing these factors; and (c) whether changes in these factors were associated with increased consumption. The same women from 15 WIC program sites were surveyed at baseline and postintervention 8 months later. Women randomized to the intervention group showed significantly greater mean change in self-efficacy, attitudes, social support, and knowledge of national consumption recommendations than control group women. Changes in all psychosocial factors were significantly associated with nutrition session attendance and increased consumption. In a hierarchical model, changes in these factors accounted for most of the intervention effect on increased consumption.

RESUMO

OBJECTIVE: To evaluate the relationship between measured weight, weight change, and 6-year mortality risk in a random sample of 648 community-dwelling women aged 65 and older from Baltimore, Maryland. MEASUREMENTS: Data were collected using a standardized questionnaire and administered in person by trained interviewers. Questionnaires were completed annually from 1984 to 1986, and body weight was measured at each interview. Weight was defined as body mass index (BMI) of low (< 23 kg/m2), average (> or = 23 kg/m2 to < or = 28 kg/m2), and high (> 28 kg/m2). Four mutually exclusive categories of weight change of at least 4.5% in BMI over the three annual interviews were developed to describe all possible weight change patterns: weight gain, weight loss, no change, and weight cycling. RESULTS: During the follow-up period, 106 women (16%) died. Women with low baseline BMI, regardless of weight change, and those who lost weight, regardless of baseline BMI had increased mortality risk. Women with average baseline BMI and weight loss had a very high mortality risk (hazard ratio (HR) 3.84, 95% Confidence interval (CI) 2.14-6.89). Women who weight cycled had increased mortality risk at low and high baseline weights, and a nonsignificant increased risk at average baseline weight (P = .069). Analyses were adjusted for age, education, smoking, alcohol usage, and pre-existing illness and included an interaction between weight change and baseline BMI. CONCLUSIONS: These results suggest that white, older, community-dwelling women are at an increased risk of mortality if they are underweight, lose weight, or weight cycle.
