ABSTRACT
CONTEXT AND

OBJECTIVE:

Interactions between body mass index (BMI), birth weight and risk parameters may contribute to diseases rather than the individual effects of each factor. However this hypothesis needs to be confirmed. This study aimed to determine to what extent variants of lipoprotein lipase (LPL) might interact with birth weight or body weight in determining the lipid profile concentrations in children and adolescents. DESIGN AND

SETTING:

Substudy of the third survey of a national surveillance system (CASPIAN-III Study) in Iran.

METHODS:

Whole blood samples (kept frozen at -70 °C) were randomly selected from 750 students aged 10-18 years. Real-time polymerase chain reaction (PCR) and high-resolution melt analysis were performed to assess S447X (rs328), HindIII (rs320) and D9N (rs1801177) polymorphisms.

RESULTS:

The AG/GG genotype in D9N polymorphism was associated with higher LDL-C (low-density lipoprotein cholesterol) and lower HDL-C (high-density lipoprotein cholesterol) concentration. Significant interactions were found for D9N polymorphism and birth weight in association with plasma HDL-C concentration, and also for D9N polymorphism and BMI in association with plasma triglyceride (TG) and HDL-C levels. HindIII polymorphism had significant association with birth weight for HDL-C concentration, and with BMI for TG and HDL-C levels. Significant interactions were found for S447X polymorphism and BMI in association with plasma TG and HDL-C concentrations.

CONCLUSION:

We found significant interactive effects from LPL polymorphisms and birth weight on HDL-C concentration, and also effects from LPL polymorphisms and BMI on TG and HDL-C concentrations.
RESUMO
RESUMO CONTEXTO E

OBJETIVO:

Interações entre índice de massa corporal (IMC), peso ao nascer e parâmetros de risco podem contribuir para doenças, em vez de efeitos individuais de cada fator. No entanto, essa hipótese precisa de confirmação. Este estudo visou determinar o quanto variantes de lipoproteína lipase (LPL) podem interagir com peso de nascimento ou peso corporal na determinação das concentrações do perfil lipídico em crianças e adolescentes. DESENHO E LOCAL Sub-estudo da terceira pesquisa de sistema nacional de vigilância (Estudo CASPIAN-III) no Irã.

MÉTODOS:

Foram selecionadas aleatoriamente amostras de sangue total (mantidas congeladas a -70 °C) de 750 estudantes com idades entre 10-18 anos. Reação de polimerase em cadeia (PCR) em tempo real e análise de fusão de alta resolução foram realizados para avaliar polimorfismo de S447X (rs328), HindIII (rs320) e D9N (rs1801177).

RESULTADOS:

Genótipo AG/GG em polimorfismo D9N foi associado com concentração maior de LDL-C (colesterol do tipo lipoproteína de baixa densidade) e menor de HDL-C (colesterol do tipo lipoproteína de alta densidade). Interações significativas foram encontradas para polimorfismo D9N e peso ao nascer em associação com concentração plasmática de HDL-C, bem como para polimorfismo D9N e IMC em associação com níveis plasmáticos de triglicérides (TG) e HDL-C. Polimorfismo HindIII teve associação significativa com peso de nascimento para concentração de HDL-C, e com IMC para níveis de TG e HDL-C. Interações significativas foram encontradas para polimorfismo S447X e IMC em associação com concentrações plasmáticas de TG e HDL-C.

CONCLUSÃO:

Encontramos efeitos interativos significativos de polimorfismo LPL e peso de nascimento sobre concentração de HDL-C, bem como efeitos de polimorfismos LPL e IMC sobre concentrações de TG e HDL-C.
