Assessment of Nutrients Intake in Pediatrics with Type 1 Diabetes and Dyslipidemia in Jordan

Background

Dyslipidemias are disorders of lipoprotein metabolism that occur during childhood and adolescence, often persist into adulthood, and increase the risk of developing atherosclerotic lesions. This study aimed to assess the potential association between nutrient intake and dyslipidemia in Jordanian pediatric patients diagnosed with type 1 diabetes mellitus.

Methods

This cross-sectional study was conducted in Amman, Jordan, and involved 90 children and adolescents diagnosed with type 1 diabetes mellitus. Caregivers provided the following data: sex, age, type and dose of insulin, age at onset of type 1 diabetes, and level of physical activity. Anthropometric measurements were obtained using calibrated scales, and CDC growth charts were used to assess participants' body weight status. Nutrient intake was estimated using a 120-item food frequency questionnaire (FFQ) previously validated in Jordanian children and adolescents. Serum lipid levels, including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), were measured. Binary logistic regression was used to assess the relationship between nutrient intake and dyslipidemia.

Results

The results indicated that 36.7% of study participants had dyslipidemia. There were no significant differences in nutrient intake between dyslipidemic and normolipidemic individuals, except for a significantly higher median intake of vitamin B12 in the dyslipidemic group compared to the normolipidemic group (3.6 versus 2.7 µg, P-value = 0.046).

Conclusion

This study found no significant association between the prevalence of dyslipidemia and nutrient intake in children and adolescents diagnosed with type 1 diabetes mellitus.

The Relationship Between Bone Mineral Density and Body Composition Among Qatari Women With High Rate of Obesity: Qatar Biobank Data

Studies have reported inconsistent results for the relationship between body composition and bone mineral density (BMD) among women, especially those with a high rate of obesity. This study aims to examine the association between BMD and body composition among Qatari women. A cross-sectional study, using data from the Qatar Biobank (QBB), was conducted on 2,000 Qatari women aged 18 and over. Measurements were taken by dual-energy X-ray absorptiometry (DEXA) for body composition [visceral fat and android fat (AF)], gynoid fat (GF), trunk fat, total fat mass (TFM), total lean mass (LM) and bone mineral density (BMD), including the lumber spine, neck, femur and total body. The participants were divided into groups of normal and low BMD, based on their T-score. Non-linear regression analysis using the restricted cubic spline method was performed according to the T-score of the total BMD for the fat mass variables. Women with a low BMD (T-score <-1) had significantly lower body composition indicators. LM was positively correlated with BMD at the spine (r = 0.29, p < 0.001), neck (r = 0.32, p < 0.001), and femur (r = 0.28, p < 0.001), as well as total BMD (r = 0.29, p < 0.001) and T-score (r = 0.31, p < 0.001), while the correlatio between TFM and BMD was negative and weak (r = -0.05, <0.017). Results of the non-linear regression indicated that components of fat distribution (TFM, AF, GF and trunk fat) were positively associated with total body T-score. In the adjusted non-liner regression, only a slight increase in T-score was recorded with an increase in FM. The association between FM and BMD was non-linear, suggesting that FM may not be a strong protector of bones among women with high rate of obesity.
