- OBJECTIVE: To analyze the effect of underweight, overweight, and obesity in relation to clinical characteristics, the risk of postoperative complications, 30-day mortality, and reoperations for recurrence after groin hernia surgery. SUMMARY OF BACKGROUND DATA: Groin hernia surgery is one of the most frequent operations performed in general surgery. Several studies have demonstrated a protective effect of overweight and obesity on the risk of developing primary groin hernia. However, obesity has also been suggested to increase the risk for recurrence of groin hernia. METHODS: Through the Swedish Hernia Register, 49,094 primary groin hernia operations were identified between January 1, 2003 and December 31, 2007. Patients were divided into 4 body mass index (BMI) groups: BMI 1, <20 kg/m2; BMI 2, 20 to 25 kg/m2; BMI 3, 25-30 kg/m2; and BMI 4, >30 kg/m2. RESULTS: Of the 49,094 patients, 3.5% had a BMI <20 kg/m2 and 5.2% were obese. Altogether, women constituted only 7.7% of the studied group, but among patients with BMI <20 kg/m2 that had surgical procedures for femoral hernia, 81.4% were women. The relation between BMI and postoperative complications was U-shaped and after adjustment for age, gender, and emergency procedure, patients with BMI <20 and >25 had a significant increased risk when compared with patients with BMI from 20 to 25. Reoperation for recurrence of groin hernia has an increased hazard ratio of 1.20 (95% confidence interval, 1.00-1.40) in overweight, which was particularly evident after open suture and preperitoneal mesh techniques. CONCLUSIONS: In this large and unselected population of patients with a first surgical procedure for groin hernia a relative dominance of female and femoral hernias presented as an emergency condition was observed in the low BMI group. The prevalence of obesity was markedly low. Both lean and obese patients had an increased risk for postoperative complications.

- AIMS: Age is one of the most powerful determinants of prognosis in myocardial infarction, but there is comparatively little recent data across the whole spectrum of acute coronary syndromes (ACS). We examined the impact of increasing age on clinical presentation and hospital outcome in a large sample of patients with ACS. METHODS AND RESULTS: Patients (n = 10 253) from the Euroheart ACS survey in 103 hospitals in 25 countries were investigated. There was a significant inverse association between the age and the likelihood of presenting with ST-elevation. For each decade of life, the odds of presenting with ST-elevation decreased by 0.82 [95% confidence interval (CI) 0.79-0.84]; P < 0.0001. Elderly patients were considerably less often treated by cardiologists, less extensively investigated, and, when presenting with ST-elevation ACS, less likely to be treated with reperfusion. Compared with patients <55 years, the odds ratios of hospital mortality were 1.87 (1.21-2.88) at age 55-64, 3.70 (2.51-5.44) at age 65-74, 6.23 (4.25-9.14) at age 75-84, and 14.5 (9.47-22.1) among patients > or =85 years, with no major differences across different types of admission or discharge diagnoses. CONCLUSION: Elderly ACS patients were less likely to present with ST-elevation but had substantial in-hospital mortality, yet they were markedly less intensively treated and investigated.

- BACKGROUND: Psychosocial factors have been reported to be independently associated with coronary heart disease. However, previous studies have been in mainly North American or European populations. The aim of the present analysis was to investigate the relation of psychosocial factors to risk of myocardial infarction in 24767 people from 52 countries. METHODS: We used a case-control design with 11119 patients with a first myocardial infarction and 13648 age-matched (up to 5 years older or younger) and sex-matched controls from 262 centres in Asia, Europe, the Middle East, Africa, Australia, and North and South America. Data for demographic factors, education, income, and cardiovascular risk factors were obtained by standardised approaches. Psychosocial stress was assessed by four simple questions about stress at work and at home, financial stress, and major life events in the past year. Additional questions assessed locus of control and presence of depression. FINDINGS: People with myocardial infarction (cases) reported higher prevalence of all four stress factors (p<0.0001). Of those cases still working, 23.0% (n=1249) experienced several periods of work stress compared with 17.9% (1324) of controls, and 10.0% (540) experienced permanent work stress during the previous year versus 5.0% (372) of controls. Odds ratios were 1.38 (99% CI 1.19-1.61) for several periods of work stress and 2.14 (1.73-2.64) for permanent stress at work, adjusted for age, sex, geographic region, and smoking. 11.6% (1288) of cases had several periods of stress at home compared with 8.6% (1179) of controls (odds ratio 1.52 [99% CI 1.34-1.72]), and 3.5% (384) of cases reported permanent stress at home versus 1.9% (253) of controls (2.12 [1.68-2.65]). General stress (work, home, or both) was associated with an odds ratio of 1.45 (99% CI 1.30-1.61) for several periods and 2.17 (1.84-2.55) for permanent stress. Severe financial stress was more typical in cases than controls (14.6% [1622] vs 12.2% [1659]; odds ratio 1.33 [99% CI 1.19-1.48]). Stressful life events in the past year were also more frequent in cases than controls (16.1% [1790] vs 13.0% [1771]; 1.48 [1.33-1.64]), as was depression (24.0% [2673] vs 17.6% [2404]; odds ratio 1.55 [1.42-1.69]). These differences were consistent across regions, in different ethnic groups, and in men and women. INTERPRETATION: Presence of psychosocial stressors is associated with increased risk of acute myocardial infarction, suggesting that approaches aimed at modifying these factors should be developed.

- AIMS: Obesity is a recognized risk factor for atrial fibrillation (AF), partly because of the association between body mass index (BMI) and atrial volume. We aimed to determine whether other factors relating to body size were related to AF. METHODS AND RESULTS: Data were derived from a random population sample of 6903 men (mean age 51.5 years) who underwent a single midlife evaluation as part of the multifactor Swedish Primary Prevention Study. A total of 1253 men (18.2%) had a subsequent hospital discharge diagnosis (principal or secondary) of AF during a maximum follow-up of 34.3 years. Body surface area (BSA) at age 20 (calculated from recalled weight and measured height) was strongly related to subsequent AF (P < 0.0001), as were midlife BMI and weight gain from age 20 to midlife (P < 0.0001). In a Cox regression model which adjusted for midlife BMI, weight gain and other risk factors, hazard ratios (HR) [95% confidence intervals (CI)] for AF for the second, third, and fourth quartile of BSA at age 20, compared with the lowest quartile, were 1.47 (95% CI, 1.22-1.76), 1.66 (95% CI, 1.38-2.00), and 2.22 (95% CI, 1.82-2.70) (P for trend <0.0001). CONCLUSION: Large body size in youth, in an era when obesity was rare, as well as weight gain from age 20 to midlife, were both independently related to the development of AF. Given the current trends not only for obesity but also for height, a substantial increase in the incidence of AF is likely.

- BACKGROUND: Previous studies have shown that risk factors commonly associated with coronary disease, stroke, and other vascular disorders also predict dementia. We investigated the longitudinal relationship between body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) and risk of hospital discharge or death certificate diagnosis of dementia. METHODS: A total of 7402 men who were 47 to 55 years old in 1970 to 1973, without prior stroke or myocardial infarction, derived from a population sample of 9998 men were prospectively followed up until 1998. Two hundred fifty-four men (3.4%) had a hospital discharge diagnosis or a death certificate diagnosis of dementia: 176 with a primary diagnosis or cause of death and 78 with a secondary diagnosis. RESULTS: The relationship between BMI and dementia as a primary diagnosis was J-shaped, and men with a BMI between 20.00 and 22.49 had the lowest risk. Subsequently, after adjustment for smoking, blood pressure, serum cholesterol level, diabetes mellitus, and social class, the risk increased linearly in men who had a BMI of 22.50 to 24.99 (multiple-adjusted hazard ratio [HR], 1.73; 95% confidence interval [CI], 0.92-3.25), 25.00 to 27.49 (HR, 1.93; 95% CI, 1.03-3.63), 27.50 to 29.99 (HR, 2.30; 95% CI, 1.18-4.47), and 30.00 or greater (HR, 2.54; 95% CI, 1.20-5.36) (P for linear trend = .03). Men with a BMI less than 20.00 had a nonsignificantly elevated risk (HR, 2.19; 95% CI, 0.77-6.25). CONCLUSIONS: A J-shaped relationship was observed between BMI and dementia, such that a BMI less than 20 and an increasing BMI of 22.5 or greater were associated with increased risk from midlife to old age of a primary hospital diagnosis of dementia. Overweight and obesity could be major preventable factors in the development of dementia.

- AIMS: To study the relation between body mass index (BMI) in young men and risk of early hospitalization with heart failure. METHODS AND RESULTS: In a prospective cohort study, men from the Swedish Conscript Registry investigated 1968-2005 (n = 1 610 437; mean age, 18.6 years were followed 5-42 years (median, 23.0 years; interquartile range, 15.0-32.0), 5492 first hospitalizations for heart failure occurred (mean age at diagnosis, 46.6 (SD 8.0) years). Compared with men with a body mass index (BMI) of 18.5-20.0 kg/m2, men with a BMI 20.0-22.5 kg/m2 had an hazard ratio (HR) of 1.22 (95% CI, 1.10-1.35), after adjustment for age, year of conscription, comorbidities at baseline, parental education, blood pressure, IQ, muscle strength, and fitness. The risk rose incrementally with increasing BMI such that men with a BMI of 30-35 kg/m2 had an adjusted HR of 6.47 (95% CI, 5.39-7.77) and those with a BMI of >/=35 kg/m2 had an HR of 9.21 (95% CI, 6.57-12.92). The multiple-adjusted risk of heart failure per 1 unit increase in BMI ranged from 1.06 (95% CI, 1.02-1.11) in heart failure associated with valvular disease to 1.20 (95% CI, 1.18-1.22) for cases associated with coronary heart disease, diabetes, or hypertension. CONCLUSION: We found a steeply rising risk of early heart failure detectable already at a normal body weight, increasing nearly 10-fold in the highest weight category. Given the current obesity epidemic, heart failure in the young may increase substantially in the future and physicians need to be aware of this.
