RESISTANCE TRAINING AND MEASURES OF INFLAMMATION IN RELATION TO BONE MINERAL DENSITY IN POSTMENOPAUSAL WOMENStanescu, Claudia Ioana January 2005 (has links)
The purpose of this study was to determine the role of body composition and fat distribution on C-reactive protein (CRP) and interleukin-6 (IL-6); determine the differences in CRP and IL-6 among HT users and non-users; determine the effect of 12-months of resistance training and resulting body composition changes on IL-6 and CRP; determine the relationship between BMD and IL-6, CRP and creatine kinase (CK). Sedentary women (N=208, age 44-66, 3-10 years postmenopausal) taking HT (N=106) or not taking HT (N=102) were randomly assigned to resistance training: HTexercise (N=55), HT-no exercise (N=45), no HT-exercise (N=53), and no HT-no exercise (N=49). The program included three weekly 60-75 minute sessions of 8 exercises performed in 2 sets of 6-8 repetitions at 70-80% of 1RM. Total fat mass (TFM), lean soft tissue mass (LSTM) and BMD were assessed by dual-energy X-ray absorptiometry (DXA). Abdominal fat mass (AFM) was assessed using DXA region of interest. For each subject, baseline and 1- year IL-6, CRP and CK were measured. High TFM, high IL-6 and HT use were independently associated with high CRP levels. A stronger relationship between IL-6 and AFM compared to TFM was found in HT users. High TFM and LSTM were significantly related to higher IL-6 levels. A stronger relationship between CRP and AFM compared to TFM was found in HT non-users. CRP was higher in HT users (5.47±5.40 mg/L) compared to non-users (2.70±3.05 mg/L) and was higher in oral (5.76±5.29 mg/L opposed; 6.14±5.97 mg/L unopposed) compared to transdermal HT users (2.65±4.44 mg/L). CRP increased slightly (p=0.077) in exercisers (0.54 ± 0.34 mg/L) not taking HT compared to controls (-0.39 ± 0.35 mg/L). Reductions in TFM were associated with reductions in IL-6 and CRP in HT users. CK was positively associated to all BMD sites at baseline. IL-6 change was positively associated with change in femur neck BMD. CRP change was inversely correlated with change in lumbar spine BMD. CK change was directly related to change in total body and femur trochanter BMD. In conclusion, reductions in TFM were accompanied by reductions in IL-6 and CRP; AFM was more strongly correlated with inflammation than TFM; 12-months of resistance training did not decrease IL-6 or CRP; IL-6 and CK were positively related to BMD, and CRP was inversely associated with BMD.

The relationship between traditional cardiovascular risk factors, body composition and C-reactive protein amongst 19 to 60 year old black women / Sonja SlabbertSlabbert, Sonja January 2004 (has links)
The prevalence of obesity has increased dramatically in the past decade. This
foreshadows an increase in the rates of morbidity and mortality from obesity related
diseases. The high prevalence of coronary heart disease (CHD) is a problem throughout
the world as well as in South Africa The process of urbanisation of Africans from rural
to urban areas is exposing the African population to Western lifestyles, with an increase
in the incidence of CHD being reported. Research is more frequently proposing that
obesity may be seen as a factor linking elevated C-reactive protein (CRP)
concentrations and atherosclerosis. CRP is an acute phase reactant and a sensitive
marker for acute and chronic inflammation of diverse causes. This poses the question
of whether the increased risk of diabetes, CHD and many other chronic diseases in the
obese might be explained by a state of chronic systemic inflammation.
The purpose of this study was, therefore, firstly to determine whether there is an
association between CRP concentrations and body composition in 19 to 60 year old
black women. Partial Pearson correlations coefficients were used to determine
associations between CRP and several body composition variables. Body mass index
(BMI), waist circumference, percentage body fat and waist-hip-ratio (WHR) were all
significantly correlated with CRP throughout the anthropometric spectrum. An analysis
of variance (ANOVA) with a Games-Howell post hoc test was done to determine
statistically significant differences among the different categories within each of the
body composition variables. Significant differences (p < 0.05) were found within the
categories of all the measured body composition variables, except for the various WHR
categories. During a signal detection analysis, BMI was identified as the best predictor
of increased CRP concentrations at a cut-off point of 27.68 kg/m2.
The second purpose of this study was to assess the relationship of CRP to traditional
cardiovascular risk factors in the study's population sample of 19 to 60 year old black
women. Pearson correlation coefficients were used to analyse log-normalized CRP
concentrations as the dependent variable in relation to several variables which form part
of the traditional risk factors for CHD. All of the variables were significantly correlated
with CRP at the level of p ≤ 0.05, except for total cholesterol and low-density
lipoprotein cholesterol. BMI, percentage body fat and fibrinogen levels were associated
with InCRP at a practically significant level of r ≥ 0.5. BMI and fibrinogen were also
found to be independently associated with InCRP with p ≤ 0.05 during a forward
stepwise multiple linear regression analysis. Within this study's population sample, it
was found that those women who presented with six traditional risk factors had a three
to five-fold increase in CRF' concentrations compared to women with three or less risk
factors. Further research is required to determine appropriate intervention programmes
which could prevent or reduce the incidence of CHD among the obese by means of
weight-loss, therefore, potentially lowering elevated CRP concentrations. / Thesis (M.Sc. (Human Movement Science))--North-West University, Potchefstroom Campus, 2005.

The relationship between traditional cardiovascular risk factors, body composition and C-reactive protein amongst 19 to 60 year old black women / Sonja SlabbertSlabbert, Sonja January 2004 (has links)
The prevalence of obesity has increased dramatically in the past decade. This
foreshadows an increase in the rates of morbidity and mortality from obesity related
diseases. The high prevalence of coronary heart disease (CHD) is a problem throughout
the world as well as in South Africa The process of urbanisation of Africans from rural
to urban areas is exposing the African population to Western lifestyles, with an increase
in the incidence of CHD being reported. Research is more frequently proposing that
obesity may be seen as a factor linking elevated C-reactive protein (CRP)
concentrations and atherosclerosis. CRP is an acute phase reactant and a sensitive
marker for acute and chronic inflammation of diverse causes. This poses the question
of whether the increased risk of diabetes, CHD and many other chronic diseases in the
obese might be explained by a state of chronic systemic inflammation.
The purpose of this study was, therefore, firstly to determine whether there is an
association between CRP concentrations and body composition in 19 to 60 year old
black women. Partial Pearson correlations coefficients were used to determine
associations between CRP and several body composition variables. Body mass index
(BMI), waist circumference, percentage body fat and waist-hip-ratio (WHR) were all
significantly correlated with CRP throughout the anthropometric spectrum. An analysis
of variance (ANOVA) with a Games-Howell post hoc test was done to determine
statistically significant differences among the different categories within each of the
body composition variables. Significant differences (p < 0.05) were found within the
categories of all the measured body composition variables, except for the various WHR
categories. During a signal detection analysis, BMI was identified as the best predictor
of increased CRP concentrations at a cut-off point of 27.68 kg/m2.
The second purpose of this study was to assess the relationship of CRP to traditional
cardiovascular risk factors in the study's population sample of 19 to 60 year old black
women. Pearson correlation coefficients were used to analyse log-normalized CRP
concentrations as the dependent variable in relation to several variables which form part
of the traditional risk factors for CHD. All of the variables were significantly correlated
with CRP at the level of p ≤ 0.05, except for total cholesterol and low-density
lipoprotein cholesterol. BMI, percentage body fat and fibrinogen levels were associated
with InCRP at a practically significant level of r ≥ 0.5. BMI and fibrinogen were also
found to be independently associated with InCRP with p ≤ 0.05 during a forward
stepwise multiple linear regression analysis. Within this study's population sample, it
was found that those women who presented with six traditional risk factors had a three
to five-fold increase in CRF' concentrations compared to women with three or less risk
factors. Further research is required to determine appropriate intervention programmes
which could prevent or reduce the incidence of CHD among the obese by means of
weight-loss, therefore, potentially lowering elevated CRP concentrations. / Thesis (M.Sc. (Human Movement Science))--North-West University, Potchefstroom Campus, 2005.

Body composition, physical activity and C-reactive protein in children : the PLAY study / Berna HarmseHarmse, Berna January 2006 (has links)
Obesity is currently the most common and costly nutritional problem in
developed countries and ten percent of the world's school-aged children are
estimated to be overweight to some extent. Low-grade systemic inflammation
is increasingly emerging as a significant component of the metabolic
syndrome. Youth in lower income families are particularly vulnerable because
of poor diet and limited opportunities for physical activity. In developing
countries obesity among youth is rising among the urban poor, possibly due to
their exposure to Westernised diets coinciding with a history of under-nutrition.
The aim of this study was to assess the association between serum CRP and
physical activity and to assess the association between serum CRP and body
composition in black high-school children from a township in the North West
Province (NWP), South Africa.
Methods and results: The study group consisted of 193 school children
between the ages 13 to 18 years (78 boys and 115 girls) residing in lkageng,
the township outside of Potchefstroom in the North West Province, South
Africa. Children were from a black ethnic group, living in a poor socioeconomic
setting. Demographic and body composition measurements were
taken and fasting blood samples were drawn for serum C-reactive protein
(CRP) measurements. The difference between serum CRP of overfat versus
girls with a normal fat percentage was non-significant (p = 0.46). Boys with
body fat percentage >20% (n=16) had .a mean serum CRP of 1.42 2.16
mg/L and for boys with a normal fat percentage (n=53) mean serum CRP was
0.89 k 1.62 mg/L. The Mann-Whitney U-test for the difference between mean
CRP of the two groups of boys was Z=1.39, p=0.16 (no significant
difference), but with a trend of higher serum CRP concentration in the boys
with higher % body fat. For the boys, the only positive partial correlation was
between serum CRP and triceps skinfold (r=0.327, p=0.045). In the girls'
group no statistically significant partial correlations were found between CRP
and body composition variables. There was no significant difference between
serum CRP concentrations of the three physical activity categories of girls.
Interestingly, there was an inverse correlation between percentage body fat and fitness in the boys' group (r=-0.509 and p= 0.008). The difference in log
CRP between activity groups showed a trend of lower serum CRP with higher
physical activity in the girls.
Conclusion: This study showed no statistically significant associations
between serum CRP and body composition, except for the positive correlation
between triceps skin fold and serum CRP in boys, or CRP and physical
activity, but clear trends were noted of an inverse association between CRP
and physical activity in the girls. / Thesis (M.Sc. (Nutrition))--North-West University, Potchefstroom Campus, 2007

Ischemic profile and cardiovascular function in African men : the SABPA study / M.E. GriffithsGriffiths, Madelein Elizabeth January 2011 (has links)
Motivation: Ischemic heart disease is the eighth leading cause of death in an
African population. Silent ischemia can be defined as an ischemic episode
without associated pain. The clinical significance of silent ischemia is growing
and can now be considered as a risk factor in the development of coronary
disease. Hypertension and associated risk factors, hypercholesterolemia and
diabetes are associated with silent ischemia. Other factors such as higher pulse
pressure, double product, heart rate and higher carotid intima-media thickness
are also associated with silent ischemia.
Urbanisation is rising in South-Africa. This new lifestyle is associated with
several risk factors including: poor diets, lower physical activity levels,
hypertension and increased smoking and alcohol abuse.
The prevalence of stroke is high among Africans, which can be due to a higher
prevalence of hypertension, diabetes and obesity.
Purpose: The purpose of this study was to determine the associations
between silent ischemia and cardiovascular function in African men. The focus
fell on hypertension and associated risk factors, higher total cholesterol levels,
and increased pulse pressure, heart rate and sub-clinical atherosclerosis.
vi
Methodology: This study constituted a population study in the North-West
province carried out on urbanized African male teachers aged between 20-60
years. The SABPA (Sympathetic activity and Ambulatory Blood Pressure in
Africans) sub-study consisted of a total of 80 African male volunteers. The
Cardiotens apparatus was placed on each participant on the first morning. This
apparatus took ambulatory blood pressure measurements as well as
Electrocardiogram measurements. Hereafter, participants continued with their
normal work day until 1700. After an overnight stay at the Metabolic unit of the
North-West University Potchefstroom campus, the apparatus was removed at
0600.
During statistical analyses, the African males were divided into groups of
participants with silent ischemia (SI) and those without silent ischemia (nSI), as
determined by the ambulatory electrocardiogram. Statistical analyses were
performed by means of the Statistica version 10 software program.
Results: In comparison with the nSI men, the SI showed the following: above
normal high sensitivity C-reactive protein and glucose, higher ambulatory blood
pressure, heart rate, pulse pressure, resting ST-segment depression and
carotid intima-media thickness. Multiple regression analyses indicated that
ambulatory silent ischemia is associated with sub-clinical atherosclerosis,
possibly increasing their stroke risk. / Thesis (M.Sc. (Physiology))--North-West University, Potchefstroom Campus, 2012.
