Lipids Health Dis 2024; 23:82. [PMID: 38509591 PMCID: PMC10953275 DOI: 10.1186/s12944-024-02074-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Accepted: 03/07/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND Dyslipidemia and abnormalities in cholesterol metabolism are commonly observed in individuals with gallstone disease. Previous research has demonstrated that dietary magnesium can influence lipid metabolism. The atherogenic index of plasma (AIP) has emerged as a novel lipid marker. This study aimed to examine the possible correlation between dietary magnesium intake and gallstones and the potential mediating role of AIP in US adults. METHODS A total of 4,841 adults were included in this study from the National Health and Nutrition Examination Survey (NHANES) conducted from 2017 to 2020. A variety of statistical techniques such as logistic regression, subgroup analysis, smoothed curve fitting, and causal mediation analysis were utilized to analyze the information collected from the participants. RESULTS In the fully adjusted model, a statistically noteworthy inverse relationship was observed between dietary magnesium intake and the presence of gallstones, as indicated by an odds ratio (OR) of 0.58 and a 95% confidence interval (CI) of (0.42, 0.81). Causal intermediary analysis revealed that the association between magnesium intake and gallstones was partially mediated by AIP, with a mediation ratio of 3.2%. CONCLUSION According to this study, dietary magnesium intake had a significant linear negative association with the prevalence of gallstones, in which AIP played a mediating role. This discovery offers novel perspectives on the prevention and management of gallstones.

Abstract
Cholesterol gallstone disease (CGD) is one of the most common digestive diseases, and it is closely associated with hepatic cholesterol metabolism. Cholesterol gallstones may be caused by abnormal hepatic cholesterol metabolism, such as excessive cholesterol biosynthesis within the liver, interfering with the uptake or export of cholesterol in the liver, and abnormal hepatic cholesterol esterification. In this review, we begin with a brief overview of the clinical diagnosis and treatment of gallstone disease (GSD). Then, we briefly describe the major processes of hepatic cholesterol metabolism and summarize the key molecular expression changes of hepatic cholesterol metabolism in patients with gallstones. We review and analyze the recent advances in elucidating the relationships between these key molecules and CGD, and some targets significantly impacting on CGD via hepatic cholesterol metabolism are also listed. We also provide a significant discussion on the relationship between CGD and nonalcoholic fatty liver disease (NAFLD). Finally, the new discoveries of some therapeutic strategies associated with hepatic cholesterol metabolism to prevent and treat CGD are summarized.

Abstract
Choledocholithiasis is a chronic common disease. The incidence of cholelithiasis is 5%-15%, of which 5%-30% are combined with Choledocholithiasis. Although endoscopic cholangiopancreatography (ERCP) + endoscopic sphincterotomy (EST) is the most common treatment procedure, which clearance rate is up to 95%, the incidence of recurrent choledocholithiasis was 4%-25%. The risk factors of recurrence after choledocholithiasis clearance are the focuses of current researches, which are caused by multiple factors. We first systematically summarize the risk factors of common bile duct stones (CBDS) recurrence into five aspects: first-episode stone related factors, congenital factors, biological factors, behavioral intervention factors, and the numbers of stone recurrence.

Abstract
Introduction. In India the prevalence of gall stone disease varies in different parts of India. Malhotra in 1996 conducted an epidemiological study in Indian Railway employees and showed that North Indians has 7 times higher prevalence of gall stones compared to South Indian employees. It is said that Gall bladder is a disease of "Fatty, Fertile, Females in their Forties". In our daily routine we observe that it is found not only in fatty females but common in average built patients also. Material and Methods. Study includes patients visiting to BPS GMC Khanpur Kalan with diagnosis of gall stone diseases and operated at our center with sample size of 135. Body mass index (BMI) and Waist to Hip ratio are calculated using their standard formulas. All data was compiled in IBM SPSS statistics (20.0). Result. Normal BMI is considered up to 25 and more than 50% patients lie in normal BMI range. Only 13% of cases lie in obese group that is BMI greater than 30. Waist to hip ratio, maximum patients that is BMI greater than 30. Waist to hip ratio, maximum patients that is (83%) lie in group more than 0.85. Minimum Waist to Hip ratio is .77 and maximum Waist to Hip ratio is 1.45. Out of 135 patients 90 patients are having high Waist to Hip ratio. Conclusion. Waist to Hip Ratio (abdominal adiposity) is better indicator of Gall stone diseases than BMI.

Abstract
Background Body mass index(BMI) is a calculation index of general obesity. Waist circumference(WC) is a measure of body-fat distribution and always used to estimate abdominal obesity. An important trait of general obesity and abdominal obesity is their propensity to coexist. Using one single measure of obesity could not estimate persons at risk for GSD precisely. Objectives This study aimed to compare the predictive values of various combination of measures for obesity(BMI, WC, waist to hip ratio) for new-onset GSD. Methods We prospectively studied the predictive values of various combination of measures for obesity for new-onset GSD in a cohort of 88,947 participants who were free of prior gallstone disease, demographic characteristics and biochemical parameters were recorded. Results 4,329 participants were identified to have GSD among 88,947 participants during 713 345 person-years of follow-up. Higher BMI, WC and waist to hip ratio (WHtR) were significantly associated with higher risks of GSD in both genders even after adjustment for potential confounders. In males, the hazard ratio for the highest versus lowest BMI, WC, WHtR were 1.63(1.47~1.79), 1.53(1.40~1.68), 1.44(1.31~1.58), respectively. In females, the hazard ratio for the highest versus lowest BMI, WC, WHtR were 2.11(1.79~2.49), 1.85(1.55~2.22), 1.84(1.55~2.19), respectively. In male group, the combination of BMI+WC improved the predictive ability of the model more clearly than other combinations after adding them to the multivariate model in turn, while for females the best predictive combination was BMI+WHtR. Conclusions Elevated BMI, WC and WHtR were independent risk factors for new-onset GSD in both sex groups after additional adjustment was made for potential confounders. In males, the combination of BMI+WC seemed to be the most predictable model to evaluate the effect of obesity on new-onset GSD, while the best combination in females was BMI+WHtR.

Abstract
BACKGROUND The prevalence of cholesterol gallstones is high in Western populations, while pigment gallstones are common in Asian populations. Dietary factors are suggested to be associated with gallstone risk, but their relationship with gallstone type has not been evaluated. This study investigated the association between diet and risk of cholesterol gallstone or pigment gallstone in a Korean population whose dietary pattern and type of gallstone were changed during the last 30 years. METHODS Patients with cholesterol (n = 40) and pigment (n = 59) gallstones were recruited after laparoscopic cholecystectomy and were compared with those of age- and sex-matched controls without gallstones (n = 99). Dietary intakes were assessed by trained dietitians using a semi-quantitative food frequency questionnaire. Multinomial logistic regression analysis was performed to calculate odds ratios and 95% confidence intervals to examine the associations between diet and risk for type of gallstones adjusted by potential confounders. RESULTS Patients with cholesterol gallstone consumed more lipid, animal lipid, beef, pork, and fried food than those with pigment gallstones and control, while patients with pigment gallstone consumed more carbohydrate and noodles than patients with cholesterol gallstone and control. In multinomial logistic regression analysis using control as reference group, dietary pattern with high consumption of beef, pork, and fried food was associated with risk of cholesterol gallstones, while there was no association between the risk of pigment gallstone and dietary pattern. In addition, control consumed more alcohol than patients with cholesterol and pigment gallstones. CONCLUSIONS The present study suggested consumption of fat from meat and fried foods increased the risk of cholesterol gallstone, and intake of carbohydrate from noodles increased the risk of pigment gallstone.

Abstract
Gallstone disease is one of the most common public health problems in the United States. Approximately 10%-20% of the national adult populations currently carry gallstones, and gallstone prevalence is rising. In addition, nearly 750,000 cholecystectomies are performed annually in the United States; direct and indirect costs of gallbladder surgery are estimated to be $6.5 billion. Cholelithiasis is also strongly associated with gallbladder, pancreatic, and colorectal cancer occurrence. Moreover, the National Institutes of Health estimates that almost 3,000 deaths (0.12% of all deaths) per year are attributed to complications of cholelithiasis and gallbladder disease. Although extensive research has tried to identify risk factors for cholelithiasis, several studies indicate that definitive findings still remain elusive. In this review, predisposing factors for cholelithiasis are identified, the pathophysiology of gallstone disease is described, and nonsurgical preventive options are discussed. Understanding the risk factors for cholelithiasis may not only be useful in assisting nurses to provide resources and education for patients who are diagnosed with gallstones, but also in developing novel preventive measures for the disease.

Abstract
Since the first cloning of the human estrogen receptor (ER) α in 1986 and the subsequent cloning of human ERβ, there has been extensive investigation of the role of estrogen/ER. Estrogens/ER play important roles not only in sexual development and reproduction but also in a variety of other functions in multiple tissues. Selective Estrogen Receptor Modulators (SERMs) are ER lignds that act as agonists or antagonists depending on the target genes and tissues, and until recently, only synthetic SERMs have been recognized. However, the discovery of the first endogenous SERM, 27-hydroxycholesterol (27HC), opened a new dimension of ER action in health and disease. In addition to the identification of 27HC as a SERM, oxysterols have been recently demonstrated as indirect modulators of ER through interaction with the nuclear receptor Liver X Receptor (LXR) β. In this review, the recent progress on these novel roles of oxysterols in ER modulation is summarized.

Abstract
BACKGROUND High carbohydrate intake has been linked to insulin resistance, obesity, and abnormal serum lipid profiles-conditions which favor gallstone formation. GOALS The aim of this study was to evaluate the effect of dietary carbohydrate intake on incident gallbladder disease, defined as biliary sludge and stones, during pregnancy. STUDY We prospectively studied 3070 pregnant women who underwent serial gallbladder ultrasound during pregnancy and at 4 to 6 weeks postpartum. All women had at least 2 study ultrasounds for comparison. A semiquantitative food frequency questionnaire was completed by subjects in the early third trimester. Multivariate logistic regression was performed to assess the risk of incident gallbladder disease across quartiles total and individual carbohydrate and individual carbohydrates (starch, sucrose, galactose, fructose, and lactose) intake. RESULTS The cumulative incidence of gallbladder disease was 10.2% by 4 to 6 weeks postpartum. The risk of incident gallbladder disease during pregnancy was significantly higher among women in the highest quartile of total carbohydrate intake versus those in the lowest quartile (odds ratio 2.09, 95% confidence interval 1.02-4.27). High intake of fructose was associated with increased risk even after additional adjustment for total carbohydrate intake (odds ratio 2.18, 95% confidence interval 1.23-3.86, comparing highest with lowest quartile). No association was found between the intake of starch, sucrose, lactose, or galactose and the risk of incident gallbladder disease. CONCLUSIONS High consumption of total carbohydrate and fructose may increase the risk of developing gallbladder disease during pregnancy. Dietary modification during pregnancy might reduce gallstone incidence during this time period.

Abstract
BACKGROUND AND AIMS Physical activity may prevent gallstones formation by reducing bile stasis and plasma triglycerides and elevating high-density lipoprotein cholesterol levels. This prospective study investigated the relationship of physical activity and symptomatic gallstones in both sexes, using a questionnaire validated against physiological measurements. METHODS A total of 25 639 volunteers, aged 40-74 years, were recruited into the European Prospective Investigation of Cancer, Norfolk and completed a questionnaire recording occupational and recreational physical activity. This questionnaire was validated earlier against measures of energy expenditure and cardio-respiratory fitness. Participants were ranked into four groups of physical activity. The cohort was monitored over 14 years for symptomatic gallstones. The primary outcome was hazard ratios (HR) of developing gallstones at 5 years, calculated using Cox regression modelling. HRs were adjusted for body mass index, alcohol, hormone replacement therapy and parity. Further analysis of a binary variable compared the highest level of physical activity against a combination of the lowest three levels. RESULTS After 5 years of follow-up, 135 participants (69.6% women) developed symptomatic gallstones. Comparing the highest level of physical activity against the lowest three levels, the multivariable analysis at 5 years was HR=0.30 (95% confidence interval=0.14-0.64, P=0.002). After 14 years the findings were attenuated (HR=0.70, 95% confidence interval=0.49-1.01, P=0.055). CONCLUSION The highest level of physical activity was associated with a 70% decreased risk of symptomatic gallstones after 5 years. This association may be causal as there are consistent experimental and epidemiological data for a protective effect. Physical activity should be accurately measured in studies investigating gallstones aetiology.

Abstract
Cholelithiasis is a major source of digestive morbidity worldwide. Cholesterol stones account for the majority of gallstones in the United States and other Western countries. The pathogenesis of cholesterol gallstone disease is multifactorial with key factors including cholesterol supersaturation of bile, altered biliary motility, and nucleation and growth of cholesterol crystals. Increasing evidence suggests that many, but not all, causative factors of cholesterol gallstones are related to insulin resistance which, in association with obesity, has reached an epidemic level worldwide. Experimental studies show that hyperinsulinemia, a key feature of insulin resistance, may cause increased hepatic cholesterol secretion and cholesterol supersaturation of bile and gallbladder dysmotility, and thereby may enhance gallstone formation. Insulin resistance syndrome can be modified by environmental factors, including dietary factors. The impact of diet on insulin sensitivity is mediated by both dietary composition and its energy content. The contribution of specific dietary elements to the prevalence and incidence of cholesterol gallstone disease has been explored in animal and human studies. There is considerable evidence to suggest that different types of fatty acids, independent of the total amount of fat consumption, affect insulin sensitivity and cholesterol gallstone disease differently. The effects of salt intake, consumption of protein and carbohydrates, and alcohol drinking on insulin resistance are controversial. Additional intervention trials and controlled experimental feeding studies are needed to further clarify these relationships and to provide useful prophylactic and therapeutic strategies.

Abstract
BACKGROUND Various saturated fatty acids have different effects on blood lipids and insulin secretion in experiments. The effect of long-term consumption of specific and different classes of saturated fatty acids on the risk of gallstone disease in humans is unknown. METHODS We prospectively studied consumption of saturated fatty acids and risk of gallstone disease in a cohort of 44,524 US men from 1986 to 2002. Intake of saturated fatty acids was assessed using a validated semiquantitative food frequency questionnaire. Newly diagnosed gallstone disease was ascertained biennially. RESULTS During 584,679 person-years of follow-up, we documented 2350 incident cases of gallstone disease, of which 1387 cases required cholecystectomy. Compared with men in the lowest quintile of dietary intake of long-chain saturated fats, after adjustment for age and other potential risk factors, the relative risk of gallstone disease for men in the highest quintile was 1.24 [95% confidence interval (CI), 1.02, 1.50, P for trend = 0.03], and the relative risk of cholecystectomy for men in the highest quintile was 1.41 (CI, 1.09, 1.82, P for trend = 0.008). Consumption of medium-chain saturated fatty acids or short-chain saturated fatty acids was unrelated to the risk. CONCLUSIONS Our results suggest that a higher consumption of long-chain saturated fatty acids may enhance the risk of gallstone disease in men.

Abstract
BACKGROUND Magnesium deficiency can cause dyslipidemia and insulin hypersecretion, which may facilitate gallstone formation. However, the effect of long-term consumption of magnesium on the risk of gallstone disease is unknown. METHODS We prospectively studied magnesium consumption and risk of gallstone disease in a cohort of 42,705 U.S. men from 1986 to 2002. Magnesium consumption was assessed using a validated semiquantitative food frequency questionnaire. Newly diagnosed gallstone disease was ascertained biennially. RESULTS We documented 2,195 incident cases of symptomatic gallstones during 560,810 person-years of follow-up. The age-adjusted relative risks (RRs) for men with total magnesium intake and dietary magnesium, when the highest and lowest quintiles were compared, were 0.67 (95% confidence interval [CI] 0.59-0.77, P for trend <0.0001) and 0.67 (CI 0.59-0.76, P for trend <0.0001), respectively. After adjusting for multiple potential confounding variables, when extreme quintiles were compared, the multivariate RR of total magnesium intake (RR 0.72, CI 0.61-0.86, P for trend = 0.006) and dietary magnesium (RR 0.68, CI 0.57-0.82, P for trend = 0.0006) remained significant with a dose-response relationship. CONCLUSIONS Our findings suggest a protective role of magnesium consumption in the prevention of symptomatic gallstone disease among men.

Abstract
BACKGROUND Insulin resistance is a risk factors for non-alcoholic fatty liver disease (NAFLD) and for gallstone disease (GD). Aims of the present study were to assess the prevalence of and factors associated with GD in unselected patients with NAFLD. METHODS A total of 161 consecutive patients with NAFLD diagnosed through compatible ultrasonography in the absence of known etiologies of liver disease (in all patients) and/or confirmed histologically (in 61 patients), was studied. Gallstone disease was diagnosed through ultrasound scanning or on the basis of previous cholecystectomy. Anthropometric and biochemical variables and concurrent diseases were compared in 32 NAFLD-GD patients and in 129 NAFLD patients without GD (controls) according to gender. RESULTS The overall prevalence of GD was 19.88%, higher in female patients (P < 0.05), who were older (P < 001). The overall percentage of GD increased with age (P < 0.05). The GD patients had higher uric acid (men), total cholesterol and apolipoprotein B (apo-B) serum concentrations (women; P < 0.05); women also had a higher prevalence of hypertriglyceridemia (P < 0.05). The age-corrected odds ratio of having GD by tertiles increased significantly with increasing uric acid (men) and with increasing total cholesterol, triglycerides and apo-B (women). At univariate continuous analysis GD was associated with insulin 120 min and uric acid in male patients; and with body mass index, insulin 120 min, apo-B, total cholesterol and triglycerides in female patients. On multivariate analysis it was found that among these factors only uric acid in men and apo-B in women were independently associated with GD in NAFLD. CONCLUSIONS The prevalence of GD in NAFLD is more elevated than reported in the general population. The factors independently associated with GD in NAFLD are different from those reported in the general population and vary according to the gender.

Abstract
BACKGROUND & AIMS High-carbohydrate diets with a high glycemic response may exacerbate the metabolic consequences of the insulin-resistance syndrome. The effect on the incidence of gallstone disease is not clear. METHODS We examined the associations between high-carbohydrate diets with a high glycemic response and the risk of cholecystectomy in a cohort of women who were aged from 35 to 61 years in 1984 and had no history of gallstone disease. As part of the Nurses' Health Study, the women reported on questionnaires mailed to them every 2 years both their carbohydrate intake and whether they had undergone cholecystectomy. RESULTS During 16 years of follow-up, we ascertained 5771 new cases of cholecystectomy. After adjusting for age and other known or suspected risk factors in a multivariate model, the relative risk for the highest compared with the lowest quintile of dietary carbohydrate was 1.35 (95% CI: 1.17-1.55, P for trend < .0001). The relative risks for the highest compared with the lowest quintile were 1.50 for glycemic load (95% CI: 1.32-1.71, P for trend < .0001) and 1.32 for glycemic index (95% CI: 1.20-1.45, P for trend < .0001). Independent positive associations were also seen for intakes of starch and sucrose. CONCLUSIONS Our findings suggest that a higher intake of carbohydrate, dietary glycemic load, and glycemic index may enhance risk of cholecystectomy in women.

Abstract
To elucidate the control of hepatic cholesterol metabolism by leptin, rats were administered IV (intravenous) leptin, ICV (intracerebroventricular) leptin or saline. A single low dose of ICV leptin was as effective as a continuous IV infusion of high-dose leptin at decreasing the activities of 3-hydroxy-3-methylglutaryl-CoA reductase and cholesterol 7alpha-hydroxylase. These results indicate that the hepatic response to leptin is transduced via the central nervous system.

Abstract
AIM: To study the effects of Radix Puerariae flavones (RPF) on liver lipid metabolism in ovariectomized (OVX) rats.
METHODS: Forty adult female Wistar rats were randomly divided into four groups: OVX group; sham-OVX group; OVX + estrogen group and OVX + RPF group. One week after operation rats of the first two groups were treated with physiological saline, rats of OVX + estrogen group with estrogen (1 mg/kg·b.w.) and rats of OVX + RPF group with RPF (100 mg/kg·b.w.), respectively for 5 weeks. After the rats were killed, their body weight, the weight of the abdominal fat and uterus were measured, and the levels of total cholesterol (TC) and triglyceride (TG) in liver homogenate were determined.
RESULTS: Compared with the sham-OVX group, the body mass of the rats in OVX group was found increased significantly; more abdominal fat in store; TC and TG in liver increased and uterine became further atrophy. As a result, the RPF was found to have an inhibitive action on those changes of various degrees.
CONCLUSION: RPF has estrogen-like effect on lipid metabolism in liver and adipose tissue.

Abstract
BACKGROUND Gallstone disease is a major source of morbidity in the developed countries. Nuts are rich in several compounds that may protect against gallstone disease. OBJECTIVE The association between nut intake and cholecystectomy was examined in a large cohort of women. DESIGN We prospectively studied nut (peanuts, other nuts, and peanut butter) consumption in relation to the risk of cholecystectomy in a cohort of 80,718 women from the Nurses' Health Study who were 30-55 y old in 1980 and had no history of gallstone disease. As part of the Nurses' Health Study, the women reported on questionnaires mailed to them every 2 y both their consumption of nuts and whether they had undergone cholecystectomy. The women were followed through 2000. RESULTS During 1,393,256 person-years of follow-up from 1980 to 2000, we documented 7831 cholecystectomies. After adjustment for age and other known or suspected risk factors, women who consumed > or =5 units of nuts (1 unit = 1 oz or 28.6 g nuts)/wk (frequent consumption) had a significantly lower risk of cholecystectomy (relative risk: 0.75; 95% CI: 0.66, 0.85; P for trend < 0.0001) than did women who never ate nuts or who ate <1 unit/mo (rare consumption). Further adjustment for fat consumption (saturated fat, trans fat, polyunsaturated fat, and monounsaturated fat) did not materially alter the relation. In analyses examining consumption of peanuts and other nuts separately, both were associated with a lower risk of cholecystectomy. CONCLUSION In women, frequent nut consumption is associated with a reduced risk of cholecystectomy.

Abstract
BACKGROUND Obesity is an established risk factor for gallstones, but whether abdominal adiposity contributes independently to the risk, particularly in men, remains unclear. OBJECTIVE The purpose of the study was to examine the associations of abdominal circumference and waist-to-hip ratio, as measures of abdominal adiposity, with the risk of symptomatic gallstone disease in men. DESIGN We prospectively studied measures of abdominal obesity in relation to the incidence of symptomatic gallstone disease in a cohort of 29 847 men who were free of prior gallstone disease and who provided complete data on waist and hip circumferences. Data on weight, height, and waist and hip circumferences were collected in 1986 and in 1987 through self-administered questionnaires. As part of the Health Professionals Follow-Up Study, men reported newly diagnosed symptomatic gallstone disease on questionnaires mailed to them every 2 y. RESULTS We documented 1117 new cases of symptomatic gallstone disease during 264 185 person-years of follow-up. After adjustment for body mass index and other known or suspected risk factors for gallstones, men with a height-adjusted waist circumference > or = 102.6 cm (40.4 in) had a relative risk of 2.29 (95% CI: 1.69, 3.11; P for trend < 0.001) compared with men with a height-adjusted waist circumference < 86.4 cm (34 in). Men with a waist-to-hip ratio > or = 0.99 had a multivariate relative risk of 1.78 (1.38, 2.28; P for trend < 0.001) compared with men with a waist-to-hip ratio < 0.89. CONCLUSIONS Our data suggest the presence of a significant association between abdominal adiposity and the incidence of symptomatic gallstone disease. As measures of abdominal adiposity, abdominal circumference and waist-to-hip ratio predict the risk of developing gallstones independently of body mass index.

Abstract
BACKGROUND Epidemiologic studies on the relationship between dietary fiber and gallstone disease are inconclusive, and the effects of different types of dietary fiber are not clear. METHODS We examined the association between long-term intake of dietary fiber as well as fiber from different sources and risk of cholecystectomy in a cohort of 69,778 women who were aged from 35 to 61 years in 1984 and had no history of gallstone disease. As part of the Nurses' Health Study, the women reported on questionnaires mailed to them every two years both their fiber intake and whether they had undergone cholecystectomy. RESULTS During 16 yr of follow-up, we documented 5,771 cases of cholecystectomy. After adjusting for age and other known or suspected risk factors in a multivariate model, compared with women in the lowest quintile of total dietary fiber intake, the relative risk of choleystectomy for those in the highest quintile was 0.87 (95% CI, 0.78-0.96, p for trend = 0.005). For a 5-g increase in total fiber intake, the multivariate relative risk was 0.94 (95% CI, 0.90-0.98). Insoluble fiber, taking soluble fiber into account in the multivariate model, was significantly associated with a reduced risk. The multivariate relative risk was 0.83 (95% CI, 0.73-0.94, p for trend = 0.009) for insoluble fiber, and was 1.01 (95% CI, 0.89-1.15, p for trend = 0.9) for soluble fiber, when extreme quintiles were compared. For a 5-g increase in intake, the relative risk was 0.90 (95% CI, 0.84-0.97) for insoluble fiber, and was 1.01 (95% CI, 0.83-1.23) for soluble fiber. CONCLUSIONS Our results suggest that increased long-term consumption of dietary fiber, particularly insoluble fiber, can reduce risk of cholecystectomy in women.
