Effects of age, gender and physical activity on plasma lipid profile

Abstract

Effects of age, gender and physical activity on plasma lipid profile Study aim: To assess the effects of gender, age and engagement in physical activities of elderly subjects on their plasma lipid profiles. Material and methods: Four groups of subjects, n = 11 each, participated in the study: young men (YM) and women (YW), aged 25 - 32 years, and sedentary, elderly men (EM) and women (EW), aged 58 - 66 years; additionally, a group of 7 women (AW), aged 60 - 65 years, who trained twice weekly (45-min sessions) for 8 months, was studied. The following concentrations of lipids in plasma were recorded: triacylglycerols (TG), total cholesterol (TC) and its fractions: HDLC and LDLC (computed), as well as the TC/HDLC ratio. Results: Lipid profiles were, generally, less favourable in elderly than in younger subjects, high HDLC values noted in active, elderly women being an exception. In elderly subjects, men's profiles were closer to those of younger subjects than in elderly women and differed significantly (p<0.001) lower for TC and LDLC compared with EW group. Triacylglycerols were within normal limits in all groups except EW; LDLC values were mostly abnormally high, the percentages of subjects having normal values ranging from 0 (YM and EW) to 27% (YW). Conclusions: The age-dependent worsening of lipid profiles increased the risk of cardiovascular diseases in sedentary elderly subjects. On the other hand, the beneficial effects of motor activities on lipid profile observed in elderly women evidence the indispensability recommending of physical exercises to the elderly.

Revisiting the dyslipidemia associated with acute leukemia

“…Previous reports have overlooked this effect and worked with leukemia populations with wider age-range for these analyses [1][2][3]5]. The agerelated differences in plasma lipid profiles of healthy individuals have been appreciated by the previous workers [43,44]. We also observed the differences in the lipid profiles of individuals from different agegroups.…”

Effects of Levothyroxine Replacement Therapy on Parameters of Metabolic Syndrome and Atherosclerosis in Hypothyroid Patients: A Prospective Pilot Study

“…On the contrary, we have observed a significant positive correlation of TSH and a negative correlation between FT4 levels and the IMCT in hypothyroid group before LT4 treatment ( Figure 4 ). Significant correlation between TSH level and lipid profile was not found probably due to some other parameters, that is, age and diet effects on lipid levels [ 32 , 33 ]. Another possibility could be because of small sample size and small effect size.…”

Evaluation of Consumption of Poultry Products Enriched withOmega-3Fatty Acids in Anthropometric, Biochemical, and Cardiovascular Parameters

“…The statistical analysis showed differences with HDL (high density lipoprotein) levels between the groups at the beginning of the study, which could be affected by several individual factors of the study population (age, diet, stress, tobacco, alcohol, physical activity, etc.) [33,45,46], which must be considered in future supplementation studies. At the end of study, the concentrations of HDL showed a tendency to increase in experimental group (51.9 to 60.1 mg/dL) and LDL (low density lipoprotein) decreased (69.9 to 62.7 mg/dL) causing the reduction of atherogenic index (2.6 to 2), while the control group showed a contrary behavior.…”
