Dislipidemia em escolares na rede privada de Belém
(2009-06) RIBAS, Simone Augusta; SILVA, Luiz Carlos Santana da
BACKGROUND: Currently, childhood dyslipidemia, associated to other non-transmissible diseases such as diabetes, hypertension and obesity, represent a significant public health problem in Brazil. OBJECTIVE: To investigate the prevalence of dyslipidemia in children and adolescents from private schools in the city of Belem, state of Para, Brazil. METHODS: Transversal and prospective study that assessed 437 schoolchildren, paired by sex. The age range was established between 6 and 19 years of age and stratified in four subgroups (6 to 9 years; 10 to 12 years; 13 to 15 years and 16 to 19 years). To obtain the anthropometric variables, weight and height were measured for the calculation of the body mass index and skin folds were measured for the calculation of body fat percentage. The serum lipoprotein profile was obtained through the measurement of total cholesterol, triglycerides, LDL-cholesterol and HDL-cholesterol after a 12-hour fasting period, by enzymatic methods. RESULTS: Of the total number of schoolchildren analyzed, 126 (28.8%) were overweight and 158 (36.2%) presented a high adiposity index. The children (33.6%) presented a higher prevalence of obesity when compared to the adolescents (10.1%; p < 0.001). Regarding the biochemical characteristics, it was observed that 214 (41%) presented some alteration in the lipid profile and that children and adolescents in the age range of 10 to 15 years were the age groups that presented the highest rates of dyslipidemia (34.6% and 25.5%), respectively. CONCLUSION: These findings demonstrate the importance of establishing an early diagnosis of the lipid profile, mainly if it is already associated to another risk factor, such as obesity.

Fatores de risco cardiovascular e fatores associados em escolares do Município de Belém, Pará, Brasil
(Escola Nacional de Saúde Pública Sergio Arouca, Fundação Oswaldo Cruz, 2014-03) RIBAS, Simone Augusta; SILVA, Luiz Carlos Santana da
This cross-sectional study aimed to identify risk factors for cardiovascular disease in a stratified cluster sample of 557 schoolchildren (6-19 years) in Belém, Pará State, Brazil. Potential risk factors were obesity, hypertension, dyslipidemia, diabetes, smoking, physical inactivity, and atherogenic diet. Socio-demographic and lifestyle variables were tested in a binary logistic regression model. The most prevalent risk factors were overweight (20.4%), dyslipidemia (48.1%), and physical inactivity (66.2%). Children below ten years of age and those from higher-income families and with higher maternal schooling showed greater odds of developing overweight; meanwhile, those with overweight were more prone to developing hypercholesterolemia and hypertriglyceridemia. The findings point to the need to implement strategies to prevent overweight in early childhood, through balanced nutrition and regular physical activity, in order to effectively reduce the prevalence of risk factors in schoolchildren.

Investigação do efeito terapêutico do Psyllium sobre a dislipidemia infanto-juvenil
(Universidade Federal do Pará, 2011-12-12) RIBAS, Simone Augusta; SILVA, Luiz Carlos Santana da; http://lattes.cnpq.br/6161491684526382; BAHIA, Marcelo de Oliveira; http://lattes.cnpq.br/3219037174956649
Psyllium is one of the richest known sources of soluble mucilaginous dietary fibre, and is considered to be a useful supplement to dietary therapy for the treatment of patients with hypercholesterolemia. The aim of this study was to assess the efficacy and safety of psyllium as a dietary supplement for the reduction of the lipidic profile of dyslipidemic Brazilian children and adolescents. Fifty-five subjects (6-19y) with mild to moderate hypercholesterolemia were evaluated in a randomised, double-blind, placebo-controlled, parallel clinical trial, conducted in two periods. During the initial dietary adaptation phase, all subjects enrolled were treated with diet low in saturated fat (<7%) and cholesterol (<200mg/day) for 6-week to prior to the treatment phase. After this period, all eligible participants were allocated randomly to two groups (control n=25 and psyllium n=30) using a computer-generated random number sequence. Over an eight-week clinical trial period, one group (psyllium) were maintained a diet low in saturated fat and cholesterol supplemented daily with 7.0g of psyllium, while the control group received the same diet plus with an equivalent amount of cellulose (placebo). At the end of the treatment period, four subjects were excluded following randomisation (lost to follow up) leaving 51 subjects (control group n= 24; psyllium group n=27, who completed the study. At the end of experiment, the psyllium group presented a significant decrease in the concentrations of total cholesterol, TC (4.1% [-0.20 mmol/L]; p=0.01) and LDL-cholesterol, LDL-c (7.2% [-0.24 mmol/L]; p<0,001). Additional reductions were observed in comparison with the control group (TC: 4.1% [-0.20 mmol/L]; p=0.007) and LDL-c: 7.8% [-0.26 mmol/L]; p=0.002). None of the participants reported any aversion to the smell, taste, appearance or texture of the psyllium, and absence serious adverse effects. Psyllium therapy shows significant efficacy on lowering of the LDL-c. It also demonstrates to be safe and acceptable for pediatric population in the study.
