Associations of Dyslipidemia with Dietary Intakes, Body Weight Status and Sociodemographic Factors among Adults in the United Arab Emirates

The Influence of the Home Food Environment on the Eating Behaviors, Family Meals, and Academic Achievement of Adolescents in Schools in the UAE

The eating behavior (EB) and habits developed during adolescence tend to persist into adulthood, with parents and caregivers playing a significant role in shaping their children's food choices. The home environment is a crucial setting for developing eating behavior during adolescence. This study aimed to explore the influence of the home food environment (HFE) and its correlates on EB, family meals (FMs), and academic achievement among adolescents in schools in the United Arab Emirates (UAE). A cross-sectional study was conducted with 304 school-aged adolescents from the UAE. The questionnaire included sociodemographic data, dietary habits, information related to the HFE (food availability and accessibility), physical activity, sleep patterns, and academic achievement. Several questionnaire items were combined to create an HFE score. These questions included the frequency of weekly family meals, meal preparation practices, and accessibility to healthy and unhealthy food products and snacks at home. The HFE score was dichotomized into favorable and unfavorable HFE scores. Similarly, EB and FM scores were generated by combining responses to various related questions. The participants' weights and heights were measured. The findings reported that more than half (55%) of the adolescents were either overweight or obese. The majority of the participants had favorable HFE (57.2%), EB (69.1%), and FM scores (58.2%). The significant correlates to the HFE were as follows: male participants whose parents attended college (OR: 0.31; 95% CI: 0.15-0.62; p < 0.001), high academic achievers (OR: 1.98; 95% CI: 1.02-3.82; p = 0.043), and those who were physically active (OR: 1.80; 95% CI: 1.14-2.85; p = 0.012), were more likely to have favorable HFE. Moreover, the HFE score showed a highly significant positive correlation with the EB score (r = 0.573, p < 0.001) and the FM score (r = 0.384, p < 0.001). These results underscore the critical role of a healthy HFE in shaping healthy positive eating behaviors and food choices among adolescents. They provide a foundation for developing effective, evidence-based policies that can impact the health and academic success of adolescents in the UAE.

Increased high-density lipoprotein cholesterol in patients with type 2 diabetes and its correlates: a cross-sectional, matched case-control survey

BACKGROUND

So far, high-density lipoprotein cholesterol (HDL-C) levels and mortality were shown to have a U-shaped relationship. Additionally, high HDL-C levels increase the risk of developing a variety of diseases. However, a paucity of data exists regarding the characteristics of people with high HDL-C levels. The aim of this study was to assess the demographics and characteristics of patients with high HDL-C levels and compare their features with normal and low HDL-C groups.

METHODS

As a cross-sectional, matched case-control study, a total of 510 patients with type 2 diabetes (T2D) were enrolled in the study and categorized into three matched groups according to their HDL-C concentrations. The studied groups were matched by their age and gender. Restricted cubic spline (RCS) curves were designed to evaluate the relationship between height, blood pressure, triglyceride, and vitamin D concentrations with the probability of having high HDL-C levels. Furthermore, violin plots were conducted to illustrate the distribution of continuous variables within each group.

RESULTS

This study showed that having high HDL-C (more than 70 mg/dL) compared to having low HDL-C (less than 40 mg/dL in men and 50 mg/dL in women) was significantly associated with height (OR 0.918, 95% CI 0.866-0.974), systolic blood pressure (SBP) (0.941, 0.910-0.972), vitamin D (0.970, 0.941-0.999), and triglyceride (0.992, 0.987-0.998) serum concentrations. Further analysis investigated that having high HDL-C levels compared to desired HDL-C levels (40 ≤ HDL-C levels < 70 in men and 50 ≤ HDL-C levels < 70 in women) was inversely associated with having SPB values greater than 130 mmHg. Besides, sufficient vitamin D levels (above 20 ng/ml) could 0.349 times decrease the odds of having high HDL-C versus normal HDL-C levels.

CONCLUSION

Sufficient vitamin D levels, SPB values higher than 130 mmHg, as well as increased triglyceride levels, were inversely associated with having high HDL levels. However, higher height values were associated with a decreased likelihood of having high HDL.

Determinants for Mediterranean diet adherence beyond the boundaries: a cross-sectional study from Sharjah, the United Arab Emirates

BACKGROUND

Substantial evidence embraced the nutrition competence of the Mediterranean diet (MD) as a healthy model for decreasing the risk of chronic diseases and increasing longevity, with the bonus of ensuring environmental sustainability. Measuring adherence to this diet is marginally investigated in the Arabian Gulf region, an area away from the Mediterranean region. The current study aimed to assess the MD adherence among adults in Sharjah/the United Arab Emirates (UAE), and to identify the most influential predictors for MD adherence among the study participants.

METHODS

A cross-sectional study design was employed using a self-reported, web-based electronic questionnaire that questioned sociodemographics, lifestyle factors, and familiarity with the MD. The MD adherence was assessed by the Mediterranean Diet Adherence Screener validated questionnaire. The adherence level was classified as low for a total score of [0-5], medium [score 6-7], and high (8-13).

RESULTS

The study included 1314 participants (age 25-52 years) comprised 822 (62.6%) females and 492 (37.4%) males. There was a moderate adherence score (5.9 ± 1.9) among the study participants. The food constituent expressed the lowest contribution to the MD was fish (9.3%), followed by fruits (12.3%), and legumes (18.3%). The multivariable linear regression analysis showed an overall significant linear trend for the association between the MD adherence score and physical activity, while nutrition information from dietitians and social media were the most two strongly related predictors for the higher adherence (β = 0.747; 95% CI 0.51-0.98, and β 0.60; 95% CI 0.269-0.93; p < 0.001, respectively). On the other side, being a smoker and from a non-Mediterranean country was associated with lower adherence scores (β = 0.538; 95% CI 0.252-0.82, p < 0.001).

CONCLUSION

The findings of the current study showed a moderate adherence, low proportion for high adherence, and a gap in the familiarity with the diet name. Being married, physically active, non-smoker, and getting nutrition information from dietitians and social media were the strongest predictors for higher adherence. It is warranted that public health and nutrition specialists/dietitians to tailor new modern approaches for promoting healthy dietary behaviours consistent with the MD.

The Role of Social Media Advertisement and Physical Activity on Eating Behaviors among the General Population in Saudi Arabia

Over the past few decades, people in Saudi Arabia have become less inclined to adopt active lifestyles and healthy eating habits due to the increasing use of digital technologies such as social media. The objective of this online-based cross-sectional study was to assess the role of social media food advertisements and physical activity on eating behaviors among the general population in Saudi Arabia (n = 471). Data were collected through a structured questionnaire, which consisted of four parts: (i) sociodemographic information, (ii) attitude towards social media, (iii) eating behaviors-related information, and (iv) exposure to and engagement with social media advertisements. The study's outcome variable, eating behaviors (healthy vs. unhealthy), was assessed using the following question: "Are you on a healthy diet (such as a balanced diet, keto, or low carb)?" A multiple binary logistic regression analysis was performed to investigate the factors that influence unhealthy eating behaviors. Approximately 79.6% of the participants had unhealthy eating behaviors. Participants who were not involved in daily physical activity were more likely to have unhealthy eating behaviors compared to their counterparts (adjusted odds ratio, AOR = 4.86). Participants who watched food ads on social media channels 1-3 times a week (AOR = 2.58) or daily (AOR = 3.49) were more likely to have unhealthy eating behaviors than their counterparts. Participants whose appetite to try foods increases always (AOR = 1.42) or usually (AOR = 2.88) after viewing ads on social media were more likely to have unhealthy eating behaviors. These findings suggest that policymakers should take immediate action to regulate food advertising policy to promote a healthy food environment across the country. Saudis should be encouraged to engage in more physical activity, which could support the maintenance of healthy eating patterns and lifestyles.

A Cross-Sectional Study of General Nutrition Knowledge among Nursing Students in the UAE

Background

Adolescence is a crucial time for establishing long-lasting healthy habits, but many university students often engage in unhealthy eating behaviors. Increased independence, social influences, and mental stress all play a role in leading to poor dietary choices that can impact overall health and well-being. It is important to have a good grasp of nutrition to make informed food choices and avoid the development of chronic illnesses.

Purpose

To assess the nutrition knowledge of nursing students and examine the interconnections between participants' beliefs about diet, disease, and weight management.

Methods

: A total of 100 nursing students participated in this descriptive cross-sectional study. Data gathering was conducted from March 2023 to May 2023 at a nursing college in the UAE. Participating students completed a self-reported validated revised general nutrition knowledge questionnaire (GNKQ-R). Descriptive statistics and Pearson's correlation were used for analysis, along with univariate and multivariate analyses as a statistical methodology to examine individual variables within the dataset independently. Cronbach's alpha coefficient of the scale in this study is 0.880. A cut-off point of 50 percent correctness was employed to signify a high level of knowledge.

Results

All participating students were female, with the majority (94%) being single. Most students (68%) had a normal mass index of 23.6, whereas 32% were overweight. The analysis showed that more than half of the students (57%) rated their overall health condition as good. The analysis also found that the only variable detected to predict the good nutrition knowledge level among studied students was having children less than 18 in the same family.

Conclusion

The results of the current study indicate that future wellness actions should prioritize increasing students' general nutrition knowledge while also considering individual and academic factors impacting NK in college.

Dyslipidemia and its predictors among adult workers in eastern Ethiopia: An institution-based cross-sectional study

INTRODUCTION

Dyslipidemia is a modifiable major risk factor for coronary heart disease. Although, the prevalence of dyslipidemia in high-income countries has been well documented, there is dearth of information about the dyslipidemia among working adults in sub-Saharan African countries including Ethiopia. Therefore, this study aimed to determine the magnitude of dyslipidemia and its associated factors among Haramaya University employees, in Eastern Ethiopia.

METHODS

A cross-sectional study was conducted among 1,200 university employees aged 20 to 60 years. Study participants were selected using a simple random sampling method. Data were collected face-to-face interview using a semi-structured questionnaire. Dyslipidemia was defined as unhealthy levels of one or more lipid profile such as high-density lipoprotein, low-density lipoprotein, triglycerides or total cholesterol. Data were entered into Epidata version 3.1 and analyzed using STATA version 16.1 software. Modified Poisson regression with robust variance was used to estimate adjusted prevalence ratios (APR) with its 95% confidence intervals. Statistical significance was declared at P-value < 0.05.

RESULTS

Of 1,164 participants, 59.6% participants had at least one lipid abnormality (i.e., 57.9% among men and 61.5% among women). Of which, 36.8% had high total cholesterol (TC), 21.6% had low high density lipoprotein cholesterol (HDL-c), 22.4% had high low density lipoprotein cholesterol (LDL-c), and 32.6% had high triglyceride (TG). We found that overweight/obesity, sedentary behavior, alcohol consumption, having hypertension and age 45 and above years were significant predictors of dyslipidemia. However, those who served fruit and vegetables more than five per day had significantly reduced prevalence ratio of dyslipidemia.

CONCLUSIONS

The high prevalent dyslipidemia among university employees is an important public health problem. Hence, tailored interventions to reduce overweight/obesity, hypertension, alcohol consumption and low fruit and vegetable intake have paramount importance to tackle dyslipidemia particularly among older age.

Prevalence of Dyslipidemia and Its Determinants Among the Adult Population of the Jazan Region

Purpose

To assess the prevalence of dyslipidemia and its determinants among adults in the Jazan region of Saudi Arabia.

Methods

This data was collected during interviews utilizing a structured questionnaire. The questionnaire measured the demographics, diagnosis with dyslipidemia, and distribution of dyslipidemia determinants among the sample, including dietary habits and lifestyle practices. A chi-square test was used to examine the statistical difference between the characteristics of individuals who had reported checking their lipid profile to those who reported never performing a lipid profile check-up among participants not diagnosed with dyslipidemia.

Results

The current study included a total of 244 participants. The median age of the participants was 27 years, most participants were female (66.8%), and about 59% had a university education or above. Approximately 40% of the participants had ever had their lipid profile checked, 20.1% of the participants had been diagnosed with dyslipidemia, and 20.9% had family history of dyslipidemia. Most of the undiagnosed participants (79.9%) had more than one risk factor for developing dyslipidemia. All the participants without a dyslipidemia diagnosis had not been meeting the recommended levels of physical activity, and more than half consumed a high-fat diet. The results of the inferential analysis indicate that among those who had not been diagnosed with dyslipidemia, participants who were older than 27 years, male, unemployed, married, had a university education or above, and a minimum monthly income of 5000 Saudi Arabia Riyals were more likely to check their lipid profile compared to other groups (p-values <0.05).

Conclusion

The findings suggest that most of the participants who had not been diagnosed with dyslipidemia are at high risk of developing dyslipidemia. About 60% of the participants had never checked their lipid profile, suggesting a need to promote routine lipid profile check-ups among individuals at high-risk for dyslipidemia.

The association of body mass index and its interaction with family history of dyslipidemia towards dyslipidemia in patients with type 2 diabetes: a cross-sectional study in Zhejiang Province, China

Objectives

This study aimed to investigate the association between body mass index (BMI) and dyslipidemia and to explore the interaction between BMI and family history of dyslipidemia towards dyslipidemia in patients with type 2 diabetes.

Methods

This cross-sectional study was conducted between March and November 2018 in Zhejiang Province, China. A total of 1,756 patients with type 2 diabetes were included, physical examination data, fasting blood samples and face-to-face questionnaire survey data were collected. Restricted cubic spline analysis was used to evaluate the association between BMI and the risk of dyslipidemia. Unconditional multivariable logistic regression was used to estimate the interaction between BMI and family history of dyslipidemia towards dyslipidemia.

Results

The prevalence of dyslipidemia was 53.7% in the study population. The risk of dyslipidemia elevated with increased BMI value (p for non-linearity <0.05). After adjusting for covariates, individuals with high BMI (≥24 kg/m²) and a family history of dyslipidemia had a 4.50-fold (95% CI: 2.99-6.78) increased risk of dyslipidemia compared to the normal reference group, which was higher than the risk associated with high BMI alone (OR = 1.83, 95% CI: 1.47-2.28) or family history of dyslipidemia alone (OR = 1.79 95% CI: 1.14-2.83). Significant additive interaction between high BMI and a family history of dyslipidemia was detected, with RERI, AP, and SI values of 1.88 (95% CI: 0.17-4.10), 0.42 (95% CI: 0.02-0.62), and 2.16 (95% CI: 1.07-4.37), respectively. However, stratified by status of diabetes control, this additive interaction was only find significant among patients with controlled diabetes.

Conclusion

Both high BMI and a family history of dyslipidemia were related with high risk of dyslipidemia. Moreover, there were synergistic interaction between these two factors. Patients with type 2 diabetes who had a family history of dyslipidemia were more susceptible to the negative impact of being overweight or obesity on dyslipidemia.

Nutrition Situation Analysis in the UAE: A Review Study

This review study aimed to assess the nutrition situation in the UAE using published data from 2010 to 2022. It highlights the gaps and challenges that prevail in addressing the nutrition-related problems in the UAE and the opportunities that have been overlooked. The available literature indicates that the UAE is burdened with more than one form of nutrition-related problems, including being underweight, being overweight, obesity, micronutrient deficiencies, and nutrition-related chronic diseases. It is clear that data on micronutrient deficiencies, protein-energy malnutrition, obesity, diabetes, and other nutrition-related diseases among the UAE population are extremely scarce. The UAE has a high prevalence of obesity and diabetes; however, limited studies have been conducted to document this nutritional phenomenon. Few examples of published data are available assessing the burden of stunting, wasting, and being underweight among children under five years of age. Despite the importance of protein-energy malnutrition, no recent publications analyze its prevalence within the UAE population. Therefore, future studies must be conducted, focusing on malnutrition. Based on the literature, and bearing in mind the magnitude of the health issues due to the UAE population's nutrition negligence, there is an urgent need to assess the population's nutrient behaviors, to aid policy decision-makers in developing and implementing effective health policies and strategies.

Longitudinal Association between Physical Activity, Blood Lipids, and Risk of Dyslipidemia among Chinese Adults: Findings from the China Health and Nutrition Surveys in 2009 and 2015

Physical activity is needed in today’s highly sedentary society. Research into Chinese trends with respect to the longitudinal association between changes in physical activity (PA) and dyslipidemia (DL) is limited. The present study assessed PA and PA-related changes associated with the level of serum lipids, and the risk of dyslipidemia stratified by gender, via a population-based longitudinal observational study among adults (>18 years old) residing in nine provinces in China. Data of 3380 adult participants, gleaned from two surveys in 2009 and 2015 used by the China Health and Nutrition Survey (CHNS), were analyzed. Three-level random intercept growth models were used to calculate the associations between total physical activity (TPA), the four activity subtypes, and changes in the level of blood lipids. Three-level logistic regression models were utilized to assess the association between TPA and the risk of DL. The highest level of TPA was observed to correlate with the lowest prevalence of DL. Compared with the lowest level of TPA, the highest level of TPA increases the concentration of HDL-C (β = 0.050, 95% CI = 0.005, 0.096) in males, and also reduces the risk in males of having low HDL-C by 31% (OR = 0.69, 95% CI = 0.52, 0.91). Occupational PA was positively associated with higher HDL-C levels in both genders (males: β = 0.004, 95% CI = 0.002, 0.007; females: β = 0.002, 95% CI = 0.000, 0.004), and leisure-time physical activity (LTPA) was negatively associated with TG levels in males. Increasing TPA benefited HDL-C levels in males, irrespective of the level of basic TPA of individuals. Physical activity (especially occupational PA) was superior in positively influencing HDL-C in males, but not in females. Leisure-time physical activity needs to be increased substantially in order to increase TPA to levels that would be beneficial to blood lipid levels and DL, irrespective of baseline TPA levels.

Thermally oxidized sunflower oil diet alters leptin/ghrelin balance and lipid profile in rats: Possible role of reactive aldehydes in dyslipidemia

Sunflower oil is a common edible oil in the world, which is highly prone to oxidative degradation during the frying process. The present study aimed to investigate the effects of products obtained from the thermal oxidation process of sunflower oil on metabolic indices, and the secretion status of leptin and ghrelin in rats. In vivo studies were designed after determining the rate of formation of active aldehydes and peroxide value in sunflower oil following 300°C in a period of 30-240 min. To this end, 36 rats in 6 separate groups were fed with 2 ml of normal saline, fresh sunflower oil, and heated oils at 30, 60, 120, and 240 min for 45 days. Finally, lipid profile changes and leptin/ghrelin secretion were examined, along with histological changes in the liver tissue. The results indicated a significant increase in serum LDL, VLDL and triglycerides, and a decrease in HDL, in the groups treated with heated oils. These changes were associated with a higher accumulation of triglycerides, active aldehydes, and histological changes in the hepatic tissue. Although the serum ghrelin level in the groups receiving heated oil did not change significantly compared to the fresh oil, the serum leptin level increased significantly in the groups receiving heated oil. According to our findings, increasing the time of sunflower oil heating enhanced the formation of active aldehydes, so that daily consumption of such oxidized oils might be associated with the occurrence of dyslipidemia, fatty liver and the development of leptin resistance. PRACTICAL APPLICATIONS: Sunflower oil is highly prone to oxidative degradation during the frying process. Increasing time of sunflower oil heating enhanced the formation of active aldehydes. Daily consumption of oxidized oils might be associated with the occurrence of dyslipidemia, fatty liver and the development of leptin resistance.
