Abstract

Purpose

This paper aims to examine impacts of the poverty alleviation relocation (PAR) program on diet quality of low-income households in China. We explore the impact mechanism of relocation on diet quality and the heterogeneous effects of different relocation modes.

Design/methodology/approach

A fixed effects model is constructed using panel data of 1126 low-income households collected over three years in eight provinces of China. The PAR program provides a natural experiment which dramatically changes the living conditions surrounding farmers. We are able to identify the causal effects of relocation on diet quality free from selection bias.

Findings

The empirical results show that the PAR program improves diet quality of low-income households and that better market access and increasing incomes induced by relocation play an important role in this improvement. Improved market access significantly reduces the over-consumption of staple foods, whereas higher income significantly reduces the intake divergences of non-staple foods. The impacts of different relocation modes on diet quality are highly heterogeneous.

Practical implications

Our findings indicate that the PAR program benefits diet quality of low-income households through greater market access and increases in total household income. Market improvements and food subsidies are conducive to improving the diet quality of the low income.

Originality/value

Despite widespread evidences of healthy diets being associated with household environments and income, selection bias remains. This paper utilizes an exogenous program to explore the causal impacts of market access and family income on diet quality and to separate their different effects.

Abstract

Purpose

The purpose of this is study is to evaluate the diet quality in nine local government areas drawn from three states of the south-east geo-political zone of Nigeria.

Design/methodology/approach

A multi-stage sampling procedure yielded 1,200 women of childbearing age (15-49 years), who responded to a multi-pass 24-hour diet recall questionnaire at the household. Diet quality (DQ) was assessed using the “diet quality index international” (DQI-I) tool with a scale of 0-100.

Findings

Mean age of respondents was 28 ± 5.6 years and body mass index was 26.81 ± 4.8 kg/m2. Majorities (96 per cent) were married, 53.2 per cent had complete secondary and 18 per cent post-secondary education, 41.7 per cent were traders, 14.3 per cent civil servants and 25.8 per cent were unemployed. Main staple foods included root and tubers, cereals, legumes and vegetables. The total DQ in the South-east was 58.8 ± 8.1 with a low “variety” (9.5 ± 3.0), poor “adequacy” (22.3 ± 4.7), good “moderation” (25.0 ± 3.8) and “overall balance” (2.0 ± 1.8).The total DQ in Imo, Enugu and Anambra were 58.6 ± 8.3, 58.8 ± 8.0 and 59.0 ± 8.1, respectively (P > 0.05).

Research limitations/implications

The study was limited to three states in South-east Nigeria; it does not give a holistic view of the DQ of women of childbearing age in Nigeria.

Originality/value

The total DQ-I score revealed average overall DQ (59/100) for South-east. However, distinct patterns of low consumption of fruits and vegetables were identified. The need for national (and cross-continental) comparison of DQ using the DQI-I tool is hereby advocated.

Abstract

Purpose

Health-related quality of life (HRQOL) is a subjective multi-dimensional concept referring to an individual’s perception of health and well-being in domains related to physical, mental, emotional and social functioning. The current study aims at investigating possible associations between dietary quality, disordered eating attitudes and HRQOL in Greek adolescents.

Design/methodology/approach

A total of 400 students (198 boys; 202 girls), 14-17 years old, were recruited from five high schools in the area of Kallithea in Athens, Greece. Standard anthropometric measurements were taken, and obesity classification was conducted using the International Obesity Task Force (IOTF) cut-off points. Students completed the KIDMED index, which evaluates the degree of adherence to the Mediterranean diet (MedDiet) as a diet quality index, the EAT-26 questionnaire, which assesses disordered eating attitudes and the KIDSCREEN-27 questionnaire for children and adolescents assessing perceived HRQOL.

Findings

Disordered eating attitudes are significantly negatively correlated with the total score of HRQOL (p < 0.01) and with the subcategories: psychological well-being (p < 0.01), parents and autonomy (p < 0.01) and school environment (p < 0.001), whereas adherence to the MedDiet was positively correlated with all the components and total score of HRQOL. Linear regression analysis revealed that adherence to the MedDiet (p < 0.05), total number of meals/day (p < 0.01) and number of meals with the family (p < 0.05) were significant predictors of HRQOL in adolescents.

Research limitations/implications

The convenient sampling of 400 students was conducted from five schools, from one municipality of Athens, Greece.

Originality/value

Adherence to the MedDiet positively affects important components of HRQOL in adolescents, whereas disordered eating attitudes has a negative effect. Identifying adolescents with low HRQOL is highly important because it could result in an early detection of individualised healthcare needs and possible non-diagnosed ill-health problems.

Abstract

Purpose

The purpose of this paper is to provide a comprehensive summary of the effect of different dietary approaches on polycystic ovary syndrome (PCOS).

Design/methodology/approach

This review represents the history of PCOS, the symptoms, diagnosis, and treatment. It also includes up‐to‐date research articles on different types of diets that have been shown some promising effects in the treatment of PCOS.

Findings

PCOS is nowadays considered the most common endocrine abnormality, with a range of 4‐12 per cent of women affected by the syndrome. It has been proven that diet, in addition to exercise and medication, plays an important role in the treatment of PCOS. The proper dietary approach for women with PCOS should focus on the PCOS symptoms and also improve weight loss, increase fertility, and decrease risks of cardiovascular diseases.

Originality/value

This paper provides accessible and comprehensive information on PCOS (since its discovery in 1935) to researchers, nutritionists, and women with PCOS who are interested in the effect of the diet on PCOS management.

Abstract

Purpose

Dietary intake is a modifiable risk factor for metabolic syndrome (MetS). Therefore, this study aims to evaluate the association between the Healthy Eating Index-2015 (HEI-2015) and MetS.

Design/methodology/approach

MetS was diagnosed among 2,326 adults. Dietary intake was assessed by a validated food frequency questionnaire. The HEI-2015 was administered to assess the diet qualities. Multivariate logistic regression was also used to evaluate the relationship of HEI-2015 with MetS and its components.

Findings

The odds of MetS was lower in women who were in the third quintile of HEI-2015 compared with those in the first quintile after adjusting for age and energy intake (OR: 0.62, CI: 0.41 to 0.93). In addition, moderate adherence to HEI-2015 reduced the odds of high fasting blood glucose levels in both men and women (OR men: 0.30, CI: 0.11 to 0.85 OR women: 0.34, CI: 0.14 to 0.79). However, these relations were not linear. Adherence to HEI-2015 had no significant relationship with the prevalence of MetS and its components in the whole population.

Originality/value

A significant relationship was observed between moderate adherence to HEI-2015 and fasting blood glucose in both men and women. Moreover, moderate adherence to this dietary pattern decreased the prevalence of MetS in women.

The purpose of this paper is to evaluate the effects of an intervention to reduce the energy density of meals in the workplace food environment.

Abstract

Purpose

The purpose of this paper is to evaluate the effects of an intervention to reduce the energy density of meals in the workplace food environment.

Design/methodology/approach

This study was conducted on a cosmetics manufacturer that employed 243 people, and was divided into three phases: diagnostic evaluation; development and testing of modifications to the energy density of the preparations; and evaluation of the results obtained. To evaluate the menus, the Meal Quality Index was used. This index consists of five components ranging from 0 to 20 points: “Adequacy of availability of vegetable and fruit”, “Carbohydrate availability”, “Total fat availability”, “Saturated fat availability” and “Menu variability”. The Kruskal‐Wallis test was used to evaluate differences in phases 1 and 3.

Findings

The classification, according to the scores for the Meal Quality Index, showed that there was an improvement in the menus, with a decrease in inadequate menus from 31 per cent to 5 per cent and in menus needing improvement from 44 per cent to 29 per cent.

Originality/value

Changes that are relatively simple to implement and reproduce regarding meal production may contribute towards controlling the obesity epidemic, through discouraging the obesogenic environment, especially among captive healthy customers such as workers who use the food services in their workplaces.

Abstract

Purpose

The purpose of the paper is to determine the effects of a hypocaloric diet with a low-glycaemic index (GI) on weight loss and postprandial blood glucose and assess both the satiety and palatability of the diet.

Design/methodology/approach

A clinical trial was conducted with ten women (mean age: 38.8±11.3 years; body mass index: 27.2±3.5 kg/m2) submitted to a hypocaloric diet, assessments were performed at baseline and after seven days of treatment.

Findings

Significant reductions were found in body weight (1.1±0.7 kg; p=0.001), triccipital skinfold (2.87±3.24 mm; p=0.021) and waist circumference (3.6±4.8 cm; p=0.041). Mean fasting and postprandial blood glucose values were 88.7±6.1 mg/dL and 91.6±9.6 mg/dL, respectively. Responses regarding satiety and palatability of the low-GI diet were predominantly “extremely satisfied” and “I liked it very much,” respectively, for all meals and throughout all seven days of the study.

Originality/value

The present study demonstrated the benefits of a low-GI diet with regard to weight loss, blood glucose control and satiety. The diet proved to be palatable, which could favor compliance with long-term treatment.

Abstract

Purpose

The purpose of this paper is to assess the Questionnaire Eating Behaviours (QEB), developed by the Science Committee of Human Nutrition of the Polish Academy of Sciences, as an instrument to examine the opinions on food and nutrition and diet quality indicators in women in various age groups.

Design/methodology/approach

The study involved 161 healthy Polish women aged 18–92, divided into four age groups to assess the QEB questionnaire, as an instrument to examine the opinions on food and nutrition and diet quality indicators.

Findings

Women provided statistically significant responses to 40 per cent of the statements in the test. In the case of 60 per cent of responses proper answers increased with the age of the participant. Questionnaire determines that people whose opinions were more compliant with nutritional knowledge more often applied the principles of proper nutrition. Dependencies between the number of points from the test of opinions about food and nutrition and the Prohealthy-Diet-Index (pHDI-8) or the sum of points from the test and the Non-healthy-Diet-Index (nHDI-8) were indicated. People who obtained the higher pHDI-8 and the lower nHDI-8 coefficient better evaluated their diet.

Originality/value

The QEB questionnaire can be an effective, quick and cheap instrument recommended to examine the association between the opinion about food and nutrition and the quality of diet of people at various ages and useful in determining the directions of further education and improvement in the quality of diet, including its assessment in large population groups.

Abstract

Purpose

The epidemic of obesity is escalating worldwide. This paper aims to focus on feasible and affordable measures to reduce obesity among sedentary persons aged 30 to 50 years, to provide suitable intervention to overcome excess body weight and to prevent further weight gain. To the authors’ knowledge, this is the first study to examine such effects in India.

Design/methodology/approach

In total, 288 sedentary office going people were motivated to reduce weight and on the basis of their being obese and willingness to participate in the study, 144 of them were selected for the intervention study. They were randomly divided into four groups. Subjects of Group I formed the control, Group II were given a high fiber and low glycemic diet mix, Group III participated in an exercise program and Group IV followed both. Anthropometric measurements were measured initially and at 30 days of interval up to 120 days, and biochemical tests were done before and after the intervention.

Findings

The subjects in Groups II, III and IV had 5 per cent reduction in anthropometric measurements. The biochemical tests revealed that the rate of decrease of mean total cholesterol and low density lipoprotein (LDL) cholesterol were greatest in Group II. In Group IV, there was maximum decrease of mean total cholesterol and high density lipoprotein (HDL) ratio, mean LDL and HDL ratio, mean fasting blood glucose and also a favorable increase of HDL cholesterol. In Group III, there was maximum increase of hemoglobin. All the central obesity measures, except body mass index, are highly and positively correlated with the biochemical parameters.

Research limitations/implications

It was observed that, in some individuals, the weight loss was 8 to 10 kg, and for a few, the weight loss was less in the range of 1 to 2 kg. This indicated that the same kind of diet and exercise brought about weight reduction to different extents due to individual response. Because of the individual differences, there is a need to highlight the response of the intervention by examining the individual variability referring to age and gender rather than pooling the mean data.

Originality/value

It was observed that the inclusion of high fiber and low glycemic diet in the intervention had a profound influence in the reduction of weight. Exercise alone may not be very effective when opted as a single measure for reducing obesity, and it can only act as a complementary program along with diet for any weight reduction program.

Abstract

Purpose

Patients with chronic obstructive pulmonary disease (COPD) suffer from many health problems including poor sleep. This paper aims to evaluate the relationship between diet quality indices (DQIs) and sleep quality in COPD.

Design/methodology/approach

The current cross-sectional study was carried on 121 COPD patients. Subjective quality of sleep was determined by Pittsburgh Sleep Quality Index (PSQI) and categorized into “poor” and “good” sleep quality. Dietary history was assessed by the DQIs. Disease status was categorized according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) Guidelines.

Findings

In total, 103 men and 18 women with a mean age of 66.1 ±10.9 were studied. The subjects were categorized into four groups based on GOLD; 3.3% of subjects were at Stage 1, 38% in Stage 2, 38% in Stage 3 and 20.7% in Stage 4. In total, 38% of subjects were good, and 62% were bad sleepers according to PSQI score. There was no significant relationship between the severity of COPD and PSQI score. We observed a significant inverse relation between PSQI total score and Mediterranean diet (MED) scale, Healthy Eating Index (HEI)-2010 and HEI-2005 (p = 0.024, 0.037 and 0.024, respectively) in males.

Originality/value

This study showed a high prevalence of poor quality of sleep and sleep disturbances among COPD patients. There was an inverse association between PSQI and sleep disorders and DQIs scores in COPD patients. Regardless of the severity of airflow obstruction, poor diet quality may constitute a risk factor for sleep quality.
