The treatment of
dyslipidemia in children is still controversial and very few trials have shown reduction in mortality after therapy14-16.
Considering the prevalence of
dyslipidemia to be 30.8 based on earlier study, [14] with absolute error at 5% and confidence level 95%, the sample size - N = [([Z.sub.a/2]).sup.2]pq/[L.sup.2].
Facing this scenario, collecting information on the prevalence of
dyslipidemia among forestry workers in the pulp and paper industry is relevant to contribute to the knowledge in this field and bring new data to help managers and workers formulate together strategies for health promotion, disease prevention and improving their quality of work life.
However, few studies contrast the results of above stated studies and show no association between psoriasis and
dyslipidemia. A population based study of National Health and Nutrition Examination Survey (NHANES 2013) documented that psoriasis was not positively associated with alternation in serum lipids.
This is in concordance with previous studies, but the patterns of
dyslipidemia in different categories and across both genders is somewhat different from that previously reported.

dyslipidemia is characterized by elevated LDL cholesterol, the predominance of small density LDL particles, elevated triglycerides, and decreased HDL cholesterol.
WHR which measures central and abdominal obesity is thus a better predictor of
dyslipidemia and its observed consequences.
Impaired glucose regulation (IGR) was defined as having FBG level ≥6.1 mmol/L and <7.0 mmol/L and/or 2h PBG level ≥7.8 mmol/L and <11.1 mmol/L.[7]
Dyslipidemia was defined as having TC ≥5.18 mmol/L (2000 mg/L) and ≤6.18 mmol/L (2390 mg/L); TG ≥1.70 mmol/L (1500 mg/L) and ≤2.25 mmol/L (1990 mg/L); LDL-C ≥3.37 mmol/L (1300 mg/L) and ≤4.12 mmol/L (1590 mg/L); and/or HDL-C <1.04 mmol/L (400 mg/L).[8] The criterion for IR was having an IR in the top tertile of the HOMA-IR defined for each gender, which was ≥2.9 in males and ≥2.2 in females.

Dyslipidemia was defined as total cholesterol >200 mg/dL and/or LDL>130 mg/kg, and/or HDL<30 mg/kg in men or HDL<45 mg/kg in women.
We excluded some cases as follows to decrease confounding factors that may affect serum lipid levels: patients with drug history of agents which could be able to change lipid profile such as statin group, fibrate group, beta blockers, steroidal hormones, contraceptive pills, cyclosporine, oral retinoids, and diuretics; pregnancy or lactation, smoking, alcoholism, diabetes, history of mustard gas poisoning, hypertension, underlying malignancy, thyroid dysfunction, eruptive form of CA; patients who had very high lipid levels in the form of familial
dyslipidemia; and patients with chronic inflammatory skin diseases such as lichen planus or psoriasis.
Previous studies demonstrated that measurement of coronary artery calcium stratified patient risk for cardiovascular disease regardless of
dyslipidemia burden or definition [5].
In a study by Freedman et al., 70% of obese or overweight children have at least one clinical cardiovascular risk factor;
dyslipidemia, high blood pressure, or insulin resistance [3].
