Abstract

Purpose

Inflammation plays a significant role in incidence of metabolic syndrome (MetS), whose risk can be reduced through modifying the diet. Considering the importance of incidence of MetS among patients with rheumatoid arthritis (RA), this study aims to determine the relationship between dietary inflammatory index (DII) and MetS in these patients.

Design/methodology/approach

This study was performed on 261 adults 35–65 years of age suffering from RA. The patients were among the participants in Ravansar non-communicable disease prospective study. DII was calculated based on food frequency questionnaire. The components of MetS were measured according to the protocol of prospective epidemiological research studies in Iran cohort. Data analysis was carried out using univariate and multivariate logistic regression model by modifying the confounding variables.

Findings

In patients with RA, prevalence of MetS was 37.5%. The mean of DII in RA patients with MetS and without MetS was −2.3 ± 1.5 and −2.2 ± 1.6, respectively, with no significant difference between two groups. After modifying the variables of age and gender, the odds of increasing waist circumference (WC) were near 1.9 times greater in the fourth quartile (pro-inflammatory diet) compared to the first quartile of DII (anti-inflammatory diet) (P = 0.03). The odds of developing hypertension was approximately 1.3 times greater in the fourth compared to the first quartile of DII (P = 0.034). The odds of developing MetS increased by 27% in the fourth quartile in comparison to the first one, though this increase was not statistically significant.

Originality/value

In RA patients, with increase in DII score, the WC and blood pressure had increased. The DII had no significant relationship with MetS. Further studies are essential across larger populations to confirm the findings.

Abstract

Purpose

Alternative Healthy Eating Index (AHEI)-2010, an index that determines the quality of a diet, was created to predict the risk of chronic diseases. Nevertheless, it is unclear whether this index can predict the risk of prostate cancer, one of the most prevalent cancers among men around the world. The study aims to investigate the association between adherence to the AHEI-2010 and the risk of prostate cancer in Iranian men.

Design/methodology/approach

The case–control study was conducted in Kermanshah, Iran in the year 2016. The study included 50 cases of Iranian men with prostate cancer and 150 healthy controls. Anthropometric indices were measured by bioelectric impedance analysis (BIA). The AHEI-2010 included 11 food components that were assessed by using a 147-item food frequency questionnaire. A multivariate logistic regression was performed to analyze the association of the AHEI-2010 (expressed as a dichotomous variable) with prostate cancer.

Findings

As per the analysis, there were no significant differences in age, body mass index (BMI) and waist-to-hip ratio (WHR) between case and control groups, statistically. After adjustment for potential confounders, the higher AHEI-2010 scores were associated with a lower risk of prostate cancer (OR AHEI > 55 vs ≤ 55 = 0.26; 95% CI: 0.11-0.63). Moreover, the Mean of AHEI scores was higher in controls than in the cases (p <0.001).

Originality/value

The authors’ findings suggest that adherence to the dietary patterns with high scores of AHEI-2010 is associated with a reduced risk of prostate cancer, so this index may be used as an effective measure to predict prostate cancer.

Abstract

Purpose

It has been suggested that there is a link between the dietary intake of certain nutrients and the risk of prostate cancer. The aim of this study is to examine the associations between dietary intakes of all nutrients and the risk of prostate cancer in Kermanshah.

Design/methodology/approach

This case-control study was conducted in Kermanshah, a province in the west of Iran in November of 2016. The sample consisted of 50 patients with confirmed prostate cancer, and 150 healthy men who matched in age with these cases and did not have any symptoms of prostate disorder were chosen as controls. Dietary intakes were collected by a semi-quantitative food frequency questionnaire that contained 147 food items and were then analyzed by Nutritionist 4 software.

Findings

After adjustment for potential confounding factor, highest tertile compared to lowest tertile of dietary vitamin E intake [odds ratio (OR) = 0.21; 95% confidence interval (CI) = 0.05-0.89], lycopene intake (OR = 0.11; 95% CI = 0.01-0.86) and magnesium intake (OR = 0.02; 95% CI = 0.01-0.55) had a protective effect on the incidence of prostate cancer. However, there were no associations between dietary intakes of fiber, vitamin A, vitamin D, vitamin B12, folate and calcium with prostate cancer.

Originality/value

The finding suggests that the dietary intakes of vitamin E, lycopene and magnesium could decrease the risk of prostate cancer. Nevertheless, dietary intake of other nutrients such as fiber, calcium, vitamins D, A, B12 and folate was not associated with prostate cancer.

Abstract

Purpose

There is some evidence that suggest a higher dietary total antioxidant capacity (DTAC) is associated with a lower risk of metabolic syndrome (MetS). Considering the conflicting results in this field, this paper aims to provide a comprehensive summary of studies on the association of DTAC and components of MetS.

Design/methodology/approach

A systematic review of articles indexed in PubMed, Scopus and Google Scholar, published from inception to September 2018, with defined keywords, was done. Duplicate or irrelevant reports were screened out and data were extracted through critical analysis. Finally, among the 353 articles, 19 articles met the inclusion criteria.

Findings

The included cohort studies revealed that higher DTAC was associated with reduced risk of MetS. Also, the association between DTAC and mortality risk of MetS was insignificant in these studies. The case–control studies showed high DTAC is inversely associated with MetS, its components and complications. The randomized controlled trials found that changes in DTAC were negatively correlated with oxidized low-density lipoprotein cholesterol and there was a positive association between DTAC and subjects’ weight and body mass index. Finally, results from the cross-sectional studies were inconsistence in this regard.

Originality/value

The assessed relationship between MetS or its components with DTAC is inconsistent in the included studies. Different sample size, dietary assessment tools, DTAC index values and geographical location may justify the observed inconsistencies. It seems that further studies are needed to reveal more confident and reliable findings.

Abstract

Purpose

Lactose intolerance (LI) is a disturbing gastrointestinal disorder with a high prevalence in all parts of the world, especially in Asian countries. The purpose of this study is to investigate the prevalence of LI in students from Zabol, Iran.

Design/methodology/approach

Based on cluster random sampling method, 887 subjects were selected for the study. Of all, 54.7 per cent of the students were boys. The mean (±SD) of age, weight and body mass index (BMI) for participants were 13.27 ± 1.14 years, 42.12 ± 10.25 kg and 18.7 ± 3.9 kg/m2, respectively. LI was assessed using a validated self-administered questionnaire. After measuring the anthropometric indices, students were asked to ingest 200cc of milk. The questionnaires were completed 2 h after the ingestion of milk.

Findings

In total, 25.8 per cent of the adolescents had LI. Of all, 1, 4.6, 11, 30.2 and 53.2 per cent of affected students had severe, relatively severe, moderate, relatively mild and mild LI, respectively. The association between LI and gender, and BMI was not significant (p > 0.05 for both); however, the association between LI and the history of LI in parents (OR = 2.06; 95 per cent CI: 1.47-2.88; p < 0.001), and breakfast consumption was significant (OR = 1.49; 95 per cent CI: 1.04-2.14; p = 0.028).

Originality/value

Although the prevalence of LI is noticeable, majority of adolescents had mild and relatively mild LI. Parents’ history and breakfast consumption are related to the rate of LI prevalence. Appropriate strategies should be considered to prevent breakfast skipping.
