Sugar-sweetened beverage intake and its associations with cardiometabolic risks among adolescents

BACKGROUND

Investigations on sugar-sweetened beverage (SSB) intake and cardiometabolic risks among Asians are scant.

OBJECTIVES

This study aimed to examine associations between SSB intake and cardiometabolic risks among Malaysian adolescents.

METHODS

Anthropometric data, blood pressure (BP), fasting blood glucose (FBG), lipid profiles and insulin levels measured involved 873 adolescents (aged 13 years). SSB intake, dietary patterns and physical activity level (PAL) were self-reported.

RESULTS

Mean SSB consumption was 177.5 mL day^-1 with significant differences among ethnicities (Malay, Chinese, Indians and Others) (p < 0.05). SSB intake was deleteriously associated with increased waist circumference, elevated triglycerides, FBG, insulin, insulin resistance and low HDL-cholesterol, independent of PAL, body mass index and dietary patterns. Significant U-shaped and inverse trends were noted between SSB intake and LDL-cholesterol and BP, respectively.

CONCLUSION

Sugar-sweetened beverage intake was unfavourably associated with cardiometabolic health outcomes among young adolescents. Concerted efforts towards healthy hydration are imperative to mitigate risk of cardiometabolic events.

Disparities in health-related quality of life among healthy adolescents in a developing country - the impact of gender, ethnicity, socio-economic status and weight status

BACKGROUND

Physical functioning and psychological resilience in adulthood is shaped during adolescence. Self-reported health-related quality of life (HRQoL) assessments during this life phase are important first-hand accounts of their well-being. This study aimed, firstly, to identify differences in HRQoL according to gender, ethnicity, socio-economic status and weight status; and secondly, to examine associations between weight status and HRQoL among an urban sample of multi-ethnic adolescents in Kuala Lumpur, Malaysia.

METHODS

A cross-sectional study involving 652 adolescents (aged 13 years) was conducted in Kuala Lumpur. Weight and height were measured. Body mass index z-scores were categorized according to the International Obesity Task Force criteria. HRQoL was assessed using the Malay version of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Univariate analyses of differences in HRQoL according to gender, ethnicity (Malays, Chinese and Indians), maternal education level and weight status were performed. Complex samples general linear model was used to examine the associations between HRQoL and weight status, adjusted for confounders.

RESULTS

Female adolescents reported significantly lower emotional functioning scores (mean, 95% confidence interval: 59.25, 57.33-61.17). When the three main ethnic groups were studied, Malay adolescents scored significantly lower emotional functioning scores (59.00, 57.13-60.87) compared with their Chinese peers. Adolescents with tertiary-educated mothers reported lower emotional functioning scores (57.45, 53.85-61.06) compared with those with primary-educated mothers. Obese adolescents reported poorer HRQoL scores with significantly impaired physical and social functioning after controlling for confounders.

CONCLUSIONS

These findings detected disparities in HRQoL among the adolescents when gender, ethnicity, maternal education level and weight status were considered. Further studies should address these health inequalities by implementing gender-specific and culturally appropriate measures to attain optimal well-being and avoid potential burden of disease.

Prescribing of antidiabetic therapies in Ireland: 10-year trends 2003-2012

BACKGROUND

Over the last decade there have been significant changes in the prescribing of antidiabetic therapies. It is of interest to know about these trends and variations in the Irish population so that future prescribing patterns can be estimated.

AIMS

To examine the trends in prescribed antidiabetic treatments, including variations across age, gender, socioeconomic status and regions in the Irish population over the last 10 years.

METHODS

The Irish national pharmacy claims database was used to identify patients ≥ 16 years dispensed antidiabetic agents (oral or insulin) from January 2003 to December 2012 through the two main community drug schemes for diabetes. The rate of prescribing per 1,000 population was calculated. Logistic regression was used to examine variations in prescribing in patients with diabetes.

RESULTS

There was a significant increase in the prescribing of fast and long-acting insulin analogues with a rapid decline in the prescribing of human insulin (p < 0.0001). Increased prescribing of metformin, incretin modulators and fixed oral combination agents was observed (p < 0.0001). Females and older aged patients were more likely to be prescribed human insulin than other insulins. Metformin was less likely while sulphonylureas were more likely to be prescribed in older than younger aged patients. Socioeconomic differences were observed in increased prescribing of the newer and more expensive antidiabetic agents in the non-means tested scheme. Regional variations were observed in the prescribing of both insulin and oral antidiabetic agents.

CONCLUSION

There has been an increase over time in the prescribing of both insulin and oral antidiabetic agents in the Irish population with increasing uptake of newer antidiabetic agents. This has implications for projecting future uptake and expenditure of these agents given the rising level of diabetes in the population.

Irish Medicines Board safety warnings: do they affect prescribing rates in primary care?

PURPOSE

To examine the impact of safety warnings issued between 2005 and 2007 by the Irish Medicines Board (IMB) on the rate of prescribing of clopidogrel, co-amoxiclav, celecoxib and haloperidol by primary care physicians in the General Medical Services (GMS) scheme across Ireland.

METHODS

This study was performed using the Irish Health Service Executive-Primary Care Reimbursement Services national prescribing database. Rate of prescribing per 1000 GMS population was calculated for each of the 12 months before and after the IMB warnings were issued to physicians. A segmented regression analysis was used to examine the change in level and trend in prescribing rates before and after the IMB warnings. Regression coefficients are presented with SEs. Significance at p < 0.05 was assumed. SPSS 16 and SAS were used for statistical analysis.

RESULTS

Prescribing of clopidogrel continued to rise in both genders following the warning. This increase was slightly higher in male patients. The prescribing of co-amoxiclav showed seasonal variation with significant autocorrelation. The rate of prescribing of celecoxib declined approximately 4  months prior to the IMB warning. A significant decrease in the level and trend of the rate of prescribing of celecoxib was observed with evident discontinuity. The IMB warning had no significant effect on the level of trend in the prescribing of haloperidol, suggesting no discontinuity.

CONCLUSIONS

Results indicate that the IMB safety warnings had inconsistent effects on the rate of prescribing of drugs considered.
