Quality Diet

Eating habits of individuals with learning and behavioral difficulties is an important and emerging area of ​​nutrition expertise. An unhealthy diet, combined with limited physical activity, is linked with an increased risk of chronic diseases and a lower quality of life. The study aims to review in a systematic way evidence on: (a) the relationship between diet quality and ADHD; and (b) the effect of three lifestyle factors, physical activity, quality of sleep, and stress on children and adults with ADHD. In December 2020, we searched for relevant articles in PubMed and Scopus. The studies included were those that assessed diet, physical activity, sleep, and stress, of children and adults with ADHD. We identified a total of eighteen studies with an invasive and observational approach that matched our research criteria. Fourteen of these studies were included in the meta-analysis. The pooled analysis showed that a high-diet quality decreases the prevalence of ADHD in children (OR: 0.43, 95% CI: 0.28-0.70), while a poor diet quality is associated with an increased risk of ADHD in both children and adults (OR: 2.24, 95% CI: 1.49-3.65). Also, a poor lifestyle indicates a higher prevalence of ADHD in both children and adults (OR: 1.90, 95% CI: 1.43-2.61). This study is limited to its ability to extract data from some of the included studies while sampling was limited due to the absence of studies in adults with ADHD. The present study suggests that a high-quality diet with increased consumption of fruits, vegetables, and fish, may be protective against ADHD in children. On top of that, a poor-quality diet with higher consumption of sugar, sweetened drinks, and junk food, as well as a lifestyle that is characterized by reduced sleep and physical activity can be associated with increased risk of ADHD, for both children and adults. The current domain needs more experimental data

AbstractIt is known that lifestyle factors affect sporadic miscarriage, but the extent of this on RPL (recurrent pregnancy loss) is less well known. A systematic review and meta-analysis was performed to assess the associations between lifestyle factors and RPL. Studies that analysed RPL in the context of BMI, smoking, alcohol and caffeine intake were included. The primary and secondary outcomes were odds of having RPL in the general population and odds of further miscarriage, respectively. Underweight and women with BMI > 25 are at higher odds of RPL in the general population (OR 1.2, 95% CI 1.12–1.28 and OR 1.21, 95% CI 1.06–1.38, respectively). In women with RPL, having BMI > 30 and BMI > 25 has increased odds of further miscarriages (OR 1.77, 95% CI 1.25–2.50 and OR 1.35, 95% CI 1.07–1.72, respectively). The quality of the evidence for our findings was low or very low. Being underweight and BMI > 25 contributes significantly to increased risk of RPL (general population). BMI > 25 or BMI > 30 increases the risk of further miscarriages (RPL population). Larger studies addressing the effects of alcohol, cigarette smoking and caffeine on the risk of RPL with optimisation of BMI in this cohort of women are now needed.

Abstract Background The ageing population in most low-and middle-income countries is accompanied by an increased risk of non-communicable diseases culminating in a poor quality of life. However, the factors accelerating this poor quality of life (QOL) have not been fully examined. Therefore, this study examined the factors influencing the quality of life of Nepali older adults.Methods Data from a previous cross-sectional study, conducted between January and April 2018 in eastern Nepal, was used. The analytical sample included 794 older adults aged ≥60 years, selected by a multi-stage cluster sampling approach. QOL was measured using the Older People’s Quality of Life tool; dichotomized as poor and good QOL. Other measures used included age, gender, ethnicity, religion, marital status, physical activity and chronic diseases such as osteoarthritis, cardiovascular disease, diabetes, chronic obstructive pulmonary disease (COPD), and depression. The factors associated with quality of life were examined using mixed-effects logistic regression.Results Seven in ten respondents (70.4%) reported a poor quality of life. At the bivariate level, increasing age, unemployment, intake of alcohol, lack of physical activity as well as osteoarthritis, COPD and depression were significantly associated with a lower likelihood of a good quality of life. The adjusted model showed that older age (AOR=0.50, p<0.05), the Christian religion (AOR=0.38, p<0.01), and being from an Indigenous, Dalit, or Madheshi background were associated with a lower likelihood of good quality of life. However, higher income of >Nrs 10,000 (AOR=3.34, p<0.001), daily physical activity (AOR=3.33, p<0.001), and the absence of osteoarthritis and depression were associated with a higher odds ratio of good quality of life.Conclusion The findings of this study echo the need to develop and implement policies aimed at improving the socio-cultural and disease conditions that catalyse poor quality of life in this population.

We aimed to assess the effect of a high-quality diet on the risk of upper gastrointestinal cancer and to evaluate the overall quality of our findings by searching PubMed, EMBASE, Web of Science, Cochrane, and the references of related articles to February 2020. Two reviewers independently retrieved the data and performed the quality assessments. We defined the highest-quality diet as that with the lowest Diet Inflammatory Index category and the highest Mediterranean Diet Score category. Overall odds ratios and 95% confidence intervals were estimated for upper gastrointestinal cancer risk comparing the highest- versus lowest-diet quality. A random-effects meta-analysis was then applied with Review Manager, and the quality of the overall findings was evaluated with the Grading of Recommendations Assessment, Development, and Evaluation approach. The highest-quality diets were significantly associated with reduced risk of upper gastrointestinal cancers, achieving odds ratios of 0.59 (95% confidence interval: 0.48–0.72) for the Diet Inflammatory Index, pooling the findings from nine studies, and 0.72 (95% confidence interval: 0.61–0.88) for the Mediterranean Diet Score, pooling the findings from 11 studies. We observed a minimum of 69% heterogeneity in the pooled results. The pooled results were graded as low quality of evidence. Although it may be possible to offer evidence-based general dietary advice for the prevention of upper gastrointestinal cancers, the evidence is currently of insufficient quality to develop dietary recommendations.

The aim of this study was to assess whether the recently developed Diet Quality Index-International (DQI-I) could be used to evaluate diet quality of a Mediterranean population. A cross-sectional nutritional survey was carried out in the Balearic Islands (Spain) between 1999 and 2000. Dietary information (replicated 24 h recall and a food frequency questionnaire), and socio-demographic and lifestyle data were collected from a representative sample of the population (n 1200: 498 males and 702 females) aged 16–65 years (response rate 77·22 %). The DQI-I was developed according to the method defined by Kim et al. (2003), and focused on four major aspects of a high-quality diet (variety, adequacy, moderation and overall balance). The percentage of adherence to the Mediterranean dietary pattern (MDP) was also calculated and correlation analysis was carried out between the DQI-I score and the percentage of adherence to the MDP. The total score of the DQI-I reached 43 % of the possible score, indicating that the Balearic diet was a poor-quality diet. Correlation analysis between the DQI-I scores and adherence to the MDP showed that the DQI-I subcategories protein, iron and calcium adequacy were negatively correlated with the MDP. Furthermore, moderation in empty calorie food consumption and overall balance subcategories were not significantly correlated with the MDP. Due to some methodological factors and cultural biases, the proposed DQI-I scoring system is not useful to evaluate the quality of this Mediterranean-type diet. Further research is needed to develop a new diet quality index adapted to the MDP.

AbstractRegular physical activity is well established to be associated with reduced risk of cardiovascular disease outcomes. Whether physical activity is associated with the future risk of atrial fibrillation (AF) remains a controversy. Using a systematic review and meta-analysis of published observational cohort studies in general populations with at least one-year of follow-up, we aimed to evaluate the association between regular physical activity and the risk of AF. Relevant studies were sought from inception until October 2020 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Extracted relative risks (RRs) with 95% confidence intervals (CIs) for the maximum versus the minimal amount of physical activity groups were pooled using random-effects meta-analysis. Quality of the evidence was assessed by GRADE. A total of 23 unique observational cohort studies comprising of 1,930,725 participants and 45,839 AF cases were eligible. The pooled multivariable-adjusted RR (95% CI) for AF comparing the most physically active versus the least physically active groups was 0.99 (0.93–1.05). This association was modified by sex: an increased risk was observed in men: 1.20 (1.02–1.42), with a decreased risk in women: 0.91 (0.84–0.99). The quality of the evidence ranged from low to moderate. Pooled observational cohort studies suggest that the absence of associations reported between regular physical activity and AF risk in previous general population studies and their aggregate analyses could be driven by a sex-specific difference in the associations – an increased risk in men and a decreased risk in women.Systematic review registration: PROSPERO 2020: CRD42020172814

The aim of this study was to assess whether the recently developed Diet Quality Index-International (DQI-I) was useful to evaluate the diet quality of a young Mediterranean population. A cross-sectional nutritional survey was carried out in southern Spain (Granada-Andalucia) from 2002 to 2005. Dietary information (24 h recall and FFQ) and socio-demographic and lifestyle data were collected from a representative sample of the population (n 288, 44·1 % females and 55·9 % males) aged 6–18 years (mean 12·88 (sd 2·78) years). DQI-I was designed according to the method of Kim et al. modified by Tur et al. for Mediterranean populations. It focused on four main characteristics of a high-quality diet (variety, adequacy, moderation and overall balance). This young population from southern Spain obtained 56·31 % of the total DQI-I score, indicating a poor-quality diet. A higher score was associated with a longer breakfast and greater physical activity. The DQI-I may require further modification for application in Mediterranean populations, differentiating between olive oil and saturated fats, among other changes. Further research is needed to develop a new diet quality index adapted to the Mediterranean diet.

AbstractIn recent years have seen increasing percentage of the elderly in the overall population. This has driven the attention to the lifestyle factors that influence the health and quality of life of this social group, including their nutrition and physical activity. Universities of the Third Age (U3A) are a valuable platform for the dissemination and broadening of the knowledge related to these topics. The nutritional habits of 61 U3A students in Poznań were evaluated on the basis of a modified KomPAN questionnaire. Their nutritional status was determined using the body mass index (BMI) and waist to hip ratio (WHR) indices. Nearly half of the respondents were overweight and 16% had first degree obesity. The WHR index in women was on average 0.8, while in men it was 1.01. Only 13% of the students declared regular eating, with 60% consuming 4-5 meals a day. Women were found to eat snacks between meals more often than men. It was also found that the majority of the elderly do not add salt to ready meals or sweeten beverages with sugars. Taking into account the observed nutritional problems and the occurrence of improper eating habits of the elderly, it is recommended to continue the education on the prevention of common diet-related diseased.

Abstract Objectives This systematic and meta-analysis review was conducted to determine the status of Iranian children and adolescents’ physical activity. Content All the related articles which were published in the major databases, including Pubmed, Scopus, Web of Science, Embase, Magiran, SID from the beginning of 2010 to the end of 2019, were reviewed by researchers. The Newcastle-Ottawa scale was also used to evaluate the quality of articles. Moreover, I 2 index and chi-square were used to assess the heterogeneity between the results. Summary 490 articles were found as a result of the search in the selected international and local databases, where finally, 10 articles were included into the meta-analysis after the elimination of the duplicated articles and applying inclusion and exclusion criteria. The results indicated that 29.5% of the girls were considered active according to WHO criteria (16.1–42.8: 95% CI) and also 20.5% of the boys (7.3–33.7: 95% CI). Outlook Overall, this study’s findings showed that a large percentage of Iranian children and adolescents do not achieve the level of physical activity recommended by the World Health Organization. This can lead to undesirable consequences for this group of population that is considered as the human capital of any country; consequently, it seems necessary to take basic measures at the micro and macro levels in order to reduce such problems in the society.
