Five hundred subjects with symptomatic limb joint osteoarthritis, who had been referred to a rheumatologist, were enrolled into a continuing study. They comprised 342 women (mean age 65.3) and 158 men (mean age 59.7), with a mean symptom duration of 15.4 years at entry. Only 31 patients (6%) had symptomatic osteoarthritis of one joint alone; however, in a further 205 (41%) the disease was limited to one site. One hundred and eighty two (36.4%) had two sites affected and 82 (16.4%) three or more sites of symptomatic osteoarthritis. Of 847 affected joints the most commonly involved were 349 (41.2%) knees, 254 (30%) hands, and 161 (19%) hips. Hip disease stood out as a separate entity, often occurring alone, and having a stronger male preponderance and different associations than osteoarthritis at other joint sites. Knee and hand disease were significantly associated in women. Obesity, hypertension, and Heberden's nodes were common. The number of sites affected, as well as the distribution, was strongly related to age as well as sex, suggesting that polyarticular osteoarthritis arises from slow acquisition of new joint sites in a non-random distribution. 'Generalised' osteoarthritis did not emerge as a distinct entity.

In summary, the relationship between risk factors and OA may differ across joints. For knees, obesity and knee injury either due to acute events or to repetitive impact loading may be the most important preventable causes of disease. Hand OA is probably also caused by repetitive use, but its association with other risk factors is unknown. Hip OA is probably different from OA in other joints, in that many cases are due to congenital and developmental abnormalities. Current inquiry focuses on generalized OA and its predictors. Future studies will look at the long-term course of OA and will focus especially on as-yet unidentified risk factors.

The decision limits of the BMI of 25 and 30 used in this paper are commonly defined as the thresholds of overweight and obesity, respectively. Our prevalence data are well comparable to those of other studies but show some special features. Thus, the frequency of moderate overweight (BMI = 25-29.9) in Freiberg is obviously higher than reported for men and women (not age-specified) in the United Kingdom, The Netherlands, United States, and Australia. Our data differ from Rosenbaum's results of a survey of heights and weights in Great Britain 1980 in the following respects: 1) Higher frequency of overweight in the middle-aged groups (30-59 years) of both sexes and 2) higher prevalence of obesity in women aged 40-59 and in men aged 30-39. Comparison of our data to those of a representative Finnish survey exhibits lower prevalence of obesity (BMI greater than or equal to 30) in the age groups 40 to 69 but a surplus prevalence of obesity in men aged 30-39. The latter seems to be a special German feature which was also seen in the DHP study. The Waist-to Hip Ratios (WHR) in this study were focused on the persons with BMI greater than 25 in whom they are important for further specification of the cardiovascular risk. The android fat distribution pattern is assumed at WHR above 1.0 in men and 0.85 in women. We found the android pattern in 20-61% of the men and in 37-76% of the women with BMI greater than 25 whereby this percentage steadily increases with age in both sexes.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of five days of antibiotic prophylaxis with cefazolin injections (beginning just before surgery) on postoperative infections (beginning just before surgery) on postoperative infectious complications was evaluated in a double-blind, randomised, placebo-controlled trial in nine centres on 2137 patients undergoing hip replacement. Antibiotic prophylaxis reduced the number of hip infections significantly from 3.3% (placebo) to 0.9% (cefazolin). Positive peroperative blood samples and positive bacteriological examination of the drain were risk factors for hip infection but the prognostic value of obesity, diabetes, or previous hip surgery was not confirmed. Development of a urinary infection was not related to hip infection. Hip infections were less common in the four centres with hypersterile operating theatres, and the benefits of prophylactic antibiotics were restricted to patients having hip replacement operations in conventional theatres.

Factors associated with hip osteoarthritis were studied in 2,490 subjects aged 55-74 years using data from the First National Health and Nutrition Examination Survey (NHANES-I). Pelvic radiographs were read for hip osteoarthritis using Kellgren-Lawrence scales; cases were defined by grade > or = 2 changes. Subjects with missing radiographs and other data and those with grade 1 radiographic changes (n = 132) were excluded from analyses. Crude and adjusted odds ratios and 95% confidence intervals (CIs) were estimated from logistic regression analyses. Overall, the crude prevalence of hip osteoarthritis was 3.1% (73 of 2,358); 42 cases were unilateral, and 31 cases were bilateral. Age was significantly associated with hip osteoarthritis (adjusted odds ratios = 1.30 (95% CI 0.60-2.81), 1.69 (95% CI 0.83-3.44), and 2.38 (95% CI 1.15-4.92) for ages 60-64, 65-69, and 70-74, respectively). Other sociodemographic factors, obesity, and fat distribution were not associated with hip osteoarthritis. Age and hip trauma were strongly associated with hip osteoarthritis among men; however, among women, no factors were significantly associated with hip osteoarthritis. Hip trauma was significantly associated with unilateral but not bilateral hip osteoarthritis, while obesity was associated with bilateral but not unilateral hip osteoarthritis. These data suggest that etiologic factors associated with hip osteoarthritis may differ for males and females and for unilateral and bilateral hip osteoarthritis.

The Normative Aging Study (NAS) recruited 2280 Boston area healthy males aged 21 to 80 in 1961 through 1970. Clinical exams have continued at 3- to 5-year intervals. Obesity was not an exclusion criterion. Stability in weight and body habitus among 867 adult participants in the NAS was evaluated at 5- and 15-year follow-ups. At study entry, age was linearly related to central adiposity [abdominal circumference (AC) and ratio of AC/Hip Breadth (HB)] throughout the entire age range (30 to 78 years) and linearly and quadratically related to weight (WT) and Body Mass Index (BMI) (kg/m2) with maximal values at age 50. Over 15 years, changes in adiposity were strongly related to age; the greatest increases were among those initially 30 to 44 years of age with decrements in several adiposity measures (BMI, AC) only among the oldest subjects (60+ at entry); significant quadratic effects of age for BMI (p < .001), WT (p < .02) and AC (p < .01). There were major secular differences; men born later were heavier and fatter at the same ages as men born earlier. Men who gained (> 1 BMI) were younger while men who lost (> 1 BMI) had greater initial central adiposity than others. Smoking cessation was independently associated with increments in both central and peripheral adiposity. Moderate alcohol intake was associated with lower gains in AC/HB ratios at 15 years compared with little or high consumption. In general, aging was associated with trends towards central adiposity which tended to plateau or decrease at the oldest ages.

A Utah family with morbid obesity was extended to include 122 persons in four generations for the purpose of characterizing anthropometric and biochemical variables in family members with and without morbid obesity. Seventy-seven subjects had blood drawn for biochemical analyses. Of the 77 subjects, 12 were morbidly obese (> or = 44.5 kg or 100 pounds overweight), 20 were between 22.5-45.4 kg (50 and 99 pounds) overweight and 45 were less than 22.5 kg (50 pounds) overweight. Sixty-two randomly-ascertained controls were used for comparisons of age- and gender-adjusted study variables. Morbidly obese subjects had mean body mass indices (BMI) of 41.0 kg/m2 (62 kg over ideal weight) compared to 25.3 kg/m2 (10 kg overweight) in the < 22.5 kg family members (p < 0.001). The < 22.5 kg family members had lower BMI than the random controls (27.6 kg/m2, p < 0.05), indicating clear bimodality of obesity within the pedigree. Percent body fat from bioelectrical impedance was 35% versus 24% in the morbidly obese and the < 22.5 kg subjects, respectively. Idealbody weight was similar among the three pedigree weight groups. Hip and waist circumferences were much larger in the morbidly obese and the waist-to-hip ratio remained significantly greater in the morbidly obese subjects compared to the < 22.5 kg group. Morbidly obese subjects had elevated triglycerides and VLDL-C levels, low HDL-levels, and normal LDL-C levels. Fasting insulin was the best predictor of morbid obesity of all biochemical and lipid measurements (odds ratio of 4.5). Fasting insulin levels and the insulin-to-glucose ratio were more than twice as high as control levels.(ABSTRACT TRUNCATED AT 250 WORDS)

To characterize people who maintain weight over long periods of time, normal weight and obese adults (n = 385) were studied over five annual visits. Subjects were classified using a +/- 5 lb change between the first and the fifth year visits to determine overall maintenance (M), with gain (G) or loss (L) being any change outside this range. This MGL status was cross-tabulated with a Fluctuation Index which counted the number of successive year-to-year weight changes of more than +/- 5 lbs (F0 through F4). True maintainers were defined as those having all weight changes within +/- 5 lbs during the 5-year period (M and F0). Nineteen percent (n = 73) of the subjects were classified as True Maintainers and included three times as many normal weight as obese subjects. Obese subjects comprised only 25% of the True Maintainer group but 60% of the Non-Maintainer group. Age had no association with Maintainer status. Standard measures of weight variability were lowest among True Maintainers and highest in Non-Maintainers. In addition, True Maintainers had lower BMI, Percent Body Fat, and Waist-Hip Ratios than Non-Maintainers. Subjects classified as Non-Maintainers were more likely to engage in dieting, by a variety of measures, than True Maintainers--this was particularly true among obese subjects. Finally, changes in total cholesterol, LDL and HDL cholesterol, and systolic and diastolic blood pressure were not reliably associated with Maintainer status, although the ordering of the group means suggested that True Maintainers had slightly healthier levels of "risk" variables. Overall, the results suggest that True Maintainers comprise a potentially important and interesting group of individuals who need further study.

Leptin concentrations in humans are increased with obesity, and women have higher leptin concentrations than men. This sex difference reflects the greater fat mass of women. However, there is evidence that factors other than the size of the adipose tissue mass contribute to serum leptin concentrations. This study was undertaken to determine whether anthropometric factors influenced leptin concentrations in our population. Leptin concentrations were measured in 375 persons from a population study of hypertension and diabetes for whom body-composition data (bio-electrical impedance analysis and anthropometry) were available. Serum leptin concentrations were more than four times higher in women than in men (18.5 +/- 13.9 compared with 3.8 +/- 3.6 ng/L, P < 0.0001). In individuals with comparable body mass indexes, these differences persisted after adjustment for either percentage fat (P < 0.05) or fat mass (P < 0.0001) by multivariate-regression analysis. After fat mass was adjusted for, the serum leptin concentration in both men and women was independent of waist circumference but in women was associated with hip circumference. Hip circumference is a proxy measure of peripheral fat and these results suggest that the larger hips of women may contribute to the sex difference in serum leptin concentration.

Hip osteoarthritis is a major cause of pain and disability. The authors explored individual risk factors for hip osteoarthritis in a population-based case-control study. The study was performed in two English health districts (Portsmouth and North Staffordshire) from 1993 to 1995. A total of 611 patients (210 men and 401 women) listed for hip replacement because of osteoarthritis over an 18-month period were compared with an equal number of controls selected from the general population and individually matched for age, sex, and family practitioner. Information about suspected risk factors was obtained by a questionnaire administered at interview and a short physical examination. Obesity (odds ratio (OR) = 1.7, 95% confidence interval (CI) 1.3-2.4; highest vs. lowest third of body mass index), previous hip injury (OR = 4.3, 95% CI 2.2-8.4), and the presence of Heberden's nodes (OR = 1.6, 95% CI 1.2-2.2) were independent risk factors for hip osteoarthritis among men and women. Hip injury was more closely related to unilateral as compared with bilateral disease. There were a negative association between cigarette smoking and osteoarthritis among men and a weak positive association with prolonged regular sporting activity. Obesity and hip injury are important independent risk factors for hip osteoarthritis, which might be amenable to primary prevention. Hip osteoarthritis may also arise as part of the polyarticular involvement found in generalized osteoarthritis.
