ABSTRACT
Diverticular disease increased steadily concomitant with elevated rates of overweight and obesity during the 20th century. Therefore, the objective of this study was to investigate whether overweight and obesity in midlife predict future diverticular disease in men.
This was a prospective cohort study of a general population of men living in Göteborg, Sweden. A communitybased sample of 7,494 men, investigated when aged 47 to 55 years, were followed from baseline in 1970 to 1973 for a maximum of 28 years. Hospitalization with a discharge diagnosis of diverticular disease according to the Swedish hospital discharge register was measured.
Totally, 112 men (1.5 percent) were hospitalized with diverticular disease. A relationship between body mass index and diverticular disease was demonstrated; men with a body mass index between 20 and 22.5 kg/m2 had the lowest risk. After adjustment for covariates, the risk increased linearly in men who had a body mass index of 22.5 to 25 (multipleadjusted hazard ratio, 2.3; 95 percent confidence interval, 0.96; 2527.5 (hazard ratio, 3 (1.27.6)), 27.530 (hazard ratio 3.2, (1.28.6)), and 30 or greater (hazard ratio 4.4, (1.612.3)) kg/m2 (P for linear trend = 0.004). Men with a body mass index of < or =20 kg/m2 had a nonsignificantly elevated risk (hazard ratio, 3 (0.712.5)). Smoking (hazard ratio, 1.6 (1.12.3) and diastolic blood pressure (hazard ratio, 1.02 (1.011.04) per mmHg) also were independently related to risk of diverticular disease.
In a large communitybased sample of middleaged men, overweight and obesity were strongly linked to future severe diverticular disease leading to hospitalization.

ABSTRACT: The incidence of diverticular disease of the colon has been rising in recent years, and the associated factors are: low ingestion of fibre, age, lack of physical activity, and obesity. A retrospective, descriptive, observational study was conducted on patients with the diagnosis of complicated diverticular disease requiring surgical or interventional treatment, for a period of 12 years. A total of 114 patients (72 males, and 42 females), age range 2891 years. More than threequarters (88 patients; 77.19%) had a body mass index (BMI) between 25 and 40 kg/m(2), and 26 patients (22.8%) had a BMI between 20 and 25 kg/m(2). Among the patients with BMI less than 25 kg/m(2), 12 patients had Hinchey 1 (46%), 8 Hinchey 2 (30.7%), 4 Hinchey 3 (15.4%), and two Hinchey 4 (7.7%). Of the patients with BMI greater than 25 kg/m(2), 19 patients had Hinchey 1 (21.6%), 24 Hinchey 2 (27.3%), 27 Hinchey 3 (30.7%), and 18 Hinchey 4 (20.45%). A statistically significant difference (P<0.001) was found between groups using MannWhitney U test. The BMI greater than 25 kg/m(2) as risk factor for complicated diverticular disease showed Odds Ratio of 3.4884 (95% confidence interval 1.279.55) with Z value of 2.44 (P=0.014). In this study, obesity was associated with an increased incidence and severity of complicated diverticular disease. Copyright © 2015 Academia Mexicana de Cirugía A.C.

 "Thus far, some studies showed the correlation between obesity and diverticulitis (Table 5).13,14,20,41 However, most studies were conducted in Western countries. "

ABSTRACT: Leftsided diverticulitis is increasing in Japan, and many studies report that leftsided diverticulitis is more likely to be severe. Therefore, it is important to identify the features and risk factors for leftsided diverticulitis. We hypothesized that leftsided diverticulitis in Japan is related to obesity and conducted a study of the features and risk factors for this disorder in Japan. Rightsided diverticulitis and leftsided diverticulitis patients (total of 215) were compared with respect to background, particularly obesityrelated factors to identify risk factors for diverticulitis. There were 166 (77.2%) rightsided diverticulitis patients and 49 (22.8%) leftsided diverticulitis patients. The proportions of obese patients (body mass index ≥25 kg/m(2), p=0.0349), viscerally obese patients (visceral fat area ≥100 cm(2), p=0.0019), patients of mean age (p=0.0003), and elderly patients (age ≥65 years, p=0.0177) were significantly higher in the leftsideddiverticulitis group than in the rightsideddiverticulitis group. The proportion of viscerally obese patients was significantly higher in the leftsideddiverticulitis group than in the leftsideddiverticulosis group (p=0.0390). This study showed that obesity, particularly visceral obesity, was a risk factor for leftsided diverticulitis in Japan.
