Addiction to sugar and its link to health morbidity: a primer for newer primary care and public health initiatives in Malaysia

Labisia pumila standardized extract (SKF7®) reduces percentage of waist circumference and waist-to-height ratio in individuals with obesity

AIM

Evidence from the literature points towards a viable choice of utilizing Labisia pumila to improve the metabolic profile in animal studies. To that end, this prospective study was designed to assess the health impact of the consumption of L. pumila standardized extract (SKF7®) on key parameters of obesity in humans such as body weight (BW), body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR).

MATERIALS AND METHODS

A dose-ranging analysis using SKF7® was conducted through a randomized, double-blind, multicentre, placebo-controlled, phase 2 clinical trial involving individuals with obesity (N = 133) between January 2020 and April 2021. The potential percentage of change was assessed in relation to BW, BMI, WC and WHtR.

RESULTS

Average treatment effect estimates (treatment group vs. placebo) show a statistically significant reduction in the percentage of change for BW (mean = -2.915; CI: -4.546, -1.285), BMI (-2.921; CI: -4.551, -1.291), WC (mean = -2.187; CI: -3.784, -0.589) and WHtR (mean = -2.294, CI: -3.908, -0.681) in the group with a total of 750 mg of SKF7® (p < .01). An incremental reduction in WC and WHtR was consistent with the gradual increase in the total daily concentration of SKF7® from 375 to 750 mg. WC and WHtR had higher effect size (f 2  = 0.11 and f 2  = 0.13 respectively) in comparison with BW and BMI.

CONCLUSIONS

SKF7® is potentially a novel therapeutic treatment for obesity, reflected by reductions in BW, BMI, WC and WHtR. The use of SKF7® suggests a dose-dependent reduction in abdominal obesity, exemplified by a decline in WC and WHtR.

Multivariable Projections of Caries-Free Prevalence and the Associated Factors from 2019 to 2030 among Schoolchildren Aged 6, 12 and 16-Year-Old in Malaysia

This study identified caries-free associated factors and conducted multivariable projections of the caries-free prevalence until 2030 among six-, 12-, and 16-year-old schoolchildren in Malaysia. It was a secondary data analysis of caries-free prevalence and potential associated factors obtained from the Health Information Management System (HIMS), Department of Statistics Malaysia (DOSM), and Food Balance Sheets (FBS). Multiple linear regression and regression with ARMA errors were employed to determine the associated factors and predict the caries-free prevalence from 2019 or 2020 until 2030 for the six-, 12-, and 16-year-old groups, respectively. Gross Domestic Product (GDP) and household income, sugar consumption, and water fluoridation were significantly associated with caries-free status, with the most impactful in all age groups being water fluoridation. With the projected values of the associated factors, the caries-free prevalence in schoolchildren of all age groups in Malaysia is predicted to increase in the next decade. Similar to the past decade, the prevalence trend will remain the highest among the 12-year-olds and the lowest among six-year-olds. Caries-free prevalence was predicted to increase by 9.10%, 15.52%, and 15.10% in the six-, 12-, and 16-year-old groups, respectively. The prevalence multiplied the highest at four times greater than in the past ten years among 16-year-olds, compared with less than 2% in the six- and 12-year-old groups. In conclusion, by factoring in economic factors, sugar consumption, water fluoridation, and age groups, the caries-free prevalence of schoolchildren in Malaysia is projected to increase at different rates in the next decade until 2030. Thus, strategic oral health plans to recognise effective promotion programmes and strengthen others for each age group are crucial.

The nexus of Sugar-Sweetened Beverages: Insights on demographics, enablers and barriers

Objectives

The study objectives were to a) explore the association between household income and nationality and Sugar-Sweetened Beverage (SSB) enablers and barriers, and b) inform public health policy and health promotion.

Study design

A Cross-sectional Study in the UAE.

Methods

Nationally representative population survey was used to capture demographic and SSB behaviour data.

Results

We recruited 7500 participants into the study and received 1290 responses (17.2% participation rate). We report statistically significant associations between household income, nationality, and enablers and barriers. In some instances, similar enablers and barriers were reported by household income and nationality.

Conclusions

There are several associations between household income, nationality and SSB enablers, and barriers. These associations should be considered for future public health policy and health promotion decision-making to reduce SSB consumption. In addition, further research is needed to explore how other demographic factors (modifying variables) are associated with SSB enablers and barriers.

•

They are statistically significant associations between household income, nationality and SSB enablers, and barriers;

•

For SSB enablers, participants agreed that SSB is readily available when they go out, and the label and packaging does not suggest SSB is harmful to health. Participants had neutral viewpoints on SSB affordability and availability at home, ease of access through mobile platforms and lack of healthier alternatives suggesting more work is needed to sway participants to disagree or strongly disagree on these aspects;

•

For SSB barriers, participants agreed that they worry about their health if they drink SSB, know about SSB that prevents them from drinking SSB, and were happy with the sugar-free alternatives. There were several areas where participants expressed a neutral viewpoint, e.g. there are no good deals/promotions to buy SSB, SSB is not available when they go out, they do not like the taste of SSB, SSB makes them sick, the label and packaging of SSB tells them it is harmful to their health, and they always have cheaper or free alternatives suggesting more work needed to sway participants to agree or strongly agre; and

•

Household income and nationality can influence SSB enablers and barriers in different ways, and in some instances, presents a nexus.

The validation of the Malay Yale Food Addiction Scale 2.0: factor structure, item analysis and model fit

Objective:

The development of a second version of the Yale Food Addiction Scale (YFAS) coincides with the latest updates in the diagnosis of addiction as documented in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. The objective of the present study was to translate the YFAS 2.0 into the Malay language and test its psychometric properties in a primary-care population.

Design:

Patients were assessed for food addiction utilizing the Malay YFAS 2.0. The participants were also assessed for eating disorder using the validated Malay Binge Eating Scale. The psychometric properties of the YFAS 2.0 were determined by analysing factor structure, overall item statistics, internal consistency and construct validity.

Setting:

Between 2017 and 2018, participants were chosen from a regional primary-care clinic in the district of Seremban, Malaysia.

Participants:

Patients (n 382) from a regional primary-care clinic.

Results:

The prevalence of food addiction was 5·0%. A two-factor structure of the YFAS was confirmed as the most optimal solution for the scale via confirmatory factor analysis. In both its diagnostic and symptom count version, the YFAS 2.0 had good internal consistency (Kuder–Richardson α > 0·80 and McDonald’s ω > 0·9).

Conclusions:

We validated a psychometrically sound Malay version of the YFAS 2.0 in a primary-care population. Both diagnostic and symptom count versions of the scale had robust psychometric properties. The questionnaire can be used to develop health promotion strategies to detect food addiction tendencies in a general population.

Dopamine genetic risk is related to food addiction and body mass through reduced reward-related ventral striatum activity

The prevalence rate of obesity continues to rise in the U.S., but effective treatment options remain elusive resulting in increased emphasis on prevention. One such area of prevention research capitalizes on the relatively novel behavioral construct of food addiction, which has been implicated in obesity. Food addiction reflects an individual's propensity for compulsive eating despite negative consequences, and shares not only symptoms with both eating and substance use disorders but also genetic and neural correlates within neural reward-circuitry modulated by dopamine. Here, we examined associations between food addiction scores, body mass index (BMI), reward-related ventral striatum activity, and a polygenic score approximating dopamine signaling in 115 non-Hispanic Caucasian young adult university students. As predicted, polygenic dopamine scores were related to ventral striatum activity, which in turn was associated with higher food addiction scores. In addition, food addiction was related to BMI. An exploratory post-hoc path analysis further indicated that polygenic scores were indirectly related to both food addiction and BMI, in part, through ventral striatum activity. Collectively, our results provide evidence supporting the utility of food addiction in weight gain prevention research by establishing links with known risk-related neural and genetic biomarkers.

Desire for Sweet Taste Unchanged After Eating: Evidence of a Dessert Mentality?

BACKGROUND/OBJECTIVES

Added sugars provide calories and desirability to foods and beverages. Our aim was to test whether desire for a sweet taste would be better maintained than a desire for other tastes for 3 hours after a test meal.

METHODS

Eighty-three young adults ate 2 slices of bread on 2 separate occasions after which they were asked to rate their desire for savory, sweet, fatty, or salty tastes and to specify the number of servings of white rice, pizza, cheese and crackers, sweet biscuits, and pasta they could consume. Desirability was assessed using 100-mm visual analog scales (VAS), with 0 mm representing no desire and 100 mm great desire.

RESULTS

When participants provided a quantitative assessment of the servings of foods that they wanted to eat following the bread meal, desire decreased on average for all foods measured, χ² (3) = 2.63, p = 0.452. Mean (95% confidence interval [CI]) change in VAS taste desirability 30 minutes after eating declined for salty (14.5 mm [10.5, 18.6]), fatty (11.2 mm [7.1, 15.2]), and savory (24.1 mm [19.7, 28.5]) tastes (p < 0.001). Desirability for sweet taste did not differ from baseline (2.4 mm [-2.3, 7.1]), and this level of desire was maintained throughout the 3-hour period.

CONCLUSIONS

The data indicate a partial disconnection between appetite and desirability for sweet taste. Physiological and psychosocial reward systems may make it difficult for people to resist sweet tasting foods and beverages. Targeting familial and cultural practices that discourage the consumption of added sugar foods might be useful to combat desire-driven food intake.
