ABSTRACT
[Abstract] Objective To study the development degree of subcutaneous fat of Guizhou dong adult. Methods The human body measurements, in October 2015 and November 2018 to Guizhou Rongjiang treble Dongzhai Miao and Dong autonomous county of Dong adult biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, supraspinale skinfold, calf skinfold six skinfold were performed, including 951 cases (male 333, female 618). Results The skinfold thickness of the trunk of Dong adults in Guizhou was greater than that of the limbs. The maximum values of the six skinfolds of male and female were found in 45-59 years old group. The minimum values of the biceps skinfold, suprailiac skinfold, supraspinale skinfold and calf skinfold of male were found in 20-44 years old group, and the minimum values were found in 60-80 years old group of female. Subscapular skinfold, suprailiac skinfold and calf skinfold were positively correlated with age in males (0. 01 < P < 0. 05), while biceps skinfold, triceps skinfold, subscapular skinfold and calf skinfold were negatively correlated with age in females (P < 0. 01). There were statistically significant differences in the 6 skinfolds between the sexes. The skinfold of females was all thicker than that of males. The percentage of body fat of female was higher than that of male. The result of cluster analysis of 13 ethnic groups showed that the six skin fold thicknesses of Dong were all smaller than those of northern ethnic groups, and close to those of southern ethnic groups. Conclusion The subcutaneous fat development in Dong is relatively high, which is similar to that in Zhuang and Dong nationalities. The skinfold thickness of Dong nationality has the characteristics of southern ethnic groups.
ABSTRACT
Objective To reveal the relationship between lipid distribution and age in Zhuang-Dong ethnic group in China. Methods By bioelectrical impedance analysis method of Zhuang-Dong 13 ethnic body composition in China, u inspection method, for the inspection of body composition differences between the sexes, the indicators by adopting the method of correlation analysis on body composition and age related analysis, variance analysis method was used to explore three body composition differences between age groups. Results The body fat rate was not high and did not reach the obesity level. Half of the men and more than half of the women had fat rates in the standard range. The body fat rate of Dong nationality and Bouyei nationality was higher, but that of Kelao nationality and Kelao nationality was lower. With age, there was no significant change in the upper limb fat rate of males, while the visceral fat rate and trunk fat rate increased, and the lower limb fat rate decreased. There was little change in the total fat rate and the lower limb fat rate. With age, there was no significant change in body mass index (BMI), total fat percentage, trunk fat percentage, and limb fat percentage. Women had a significantly higher percentage of body fat than men. There was no significant correlation between left and right upper limb fat rate and age in males, body fat rate, visceral fat level and trunk fat rate were significantly positively correlated with age, and left and right lower limb fat rate and age were significantly negatively correlated. The left upper limb fat rate, left and right lower limb fat rate were negatively correlated with age, and the trunk fat rate was positively correlated with age. There was no significant correlation between age and total female lipid. Conclusion The body fat of Zhuang-Dong ethnic group in China is much thinner than that of north Asian ethnic group, and it has the characteristic of sebum development level of southern Chinese ethnic group.
ABSTRACT
BACKGROUND:Obesity is a risk factor for many chronic diseases. In recent years, the obesity rate of college students in my country has been on the rise. Undergraduates are under great academic pressure and have little exercise time, and their obesity needs attention from the society. Studies have found that different intensities of physical activities improve fat composition of obese or overweight people of different sexes to different extent. OBJECTIVE: To analyze the characteristics of daily physical activity and fat distribution in college students, and to explore the correlation between physical activity and fat distribution. METHODS: In total, 1 875 college students from a college of Guangxi Province were randomly selected using random sampling method. The International Physical Activity Questionnaire (IPAQ) (Chinese version) to collect their physical activity data for the past week, and a body composition measuring instrument was used to measure their fat parameter. Male and female college students were divided into three groups according to body fat rate. Male college students: ≤ 10%, 11%-21%, ≥ 22%; female college students: ≤ 20%, 21%-34%, ≥ 35%. SPSS 23.0 was used for data processing and analysis. RESULTS AND CONCLUSION: (1) Fat mass: In male college students, total fat mass > subcutaneous fat mass > trunk fat mass > lower limb fat mass > visceral fat mass > upper limb fat mass; in female college students, total fat mass > subcutaneous fat mass > trunk fat mass > lower limb fat mass > upper limb fat mass > visceral fat mass. (2) Physical activity: in college students, low-intensity physical activity > medium-intensity physical activity > high-intensity physical activity. (3) Body fat rate: In male college students, low-intensity, medium-intensity and total physical activity were highest in the < 10% group, followed by 11%-21% group and ≥ 22% group in turn (all P < 0.05), and the high-intensity physical activity in the < 10% group was higher than that in the 11%-21% group and ≥22% group (all P < 0.05). In female college students, low-intensity and medium-intensity physical activity in the < 20% group was higher than that in the 21%-34% group and ≥ 35% group (all P < 0.05), and the high-intensity and total physical activity was highest in the < 20% group, followed by 21%-34% group and ≥ 35% group in turn (all P < 0.05). (4) Correlation analysis: In male college students, low-intensity physical activity was significantly negatively correlated with total fat mass, visceral fat content, trunk fat mass, and lower limb fat mass (all r < 0, all P < 0.05), and other fat parameters were significantly negatively correlated with medium-intensity, high-intensity and total physical activity (all r < 0, all P < 0.05). In female college students, visceral fat mass was significantly negatively correlated with high-intensity physical activity (r < 0, P < 0.01), and trunk fat mass was significantly negatively correlated with high-intensity physical activity and total physical activity (both r < 0, both P < 0.01), and other fat parameters were significantly negatively correlated with low-intensity physical activity, medium-intensity physical activity, high-intensity physical activity, and total physical activity (all r < 0, all P < 0.05). To conclude, there are sex differences in physical activity and fat distribution among college students, and the fat rate of the group with active physical activity is low. The increase in physical activity of various strengths is beneficial to the reduction of body fat. In male college students, subcutaneous fat mass and upper limb fat mass are mainly affected by medium-intensity and high-intensity physical activity, and in female college students, visceral fat mass and trunk fat mass are mainly affected by high-intensity physical activity.
ABSTRACT
Resumen:
Objetivo: determinar la influencia del consumo de macronutrientes (CM) en el porcentaje de grasa corporal (PGC) y del PGC sobre la presión arterial (PA).
Metodología: análisis secundario, diseño descriptivo correlacional. Se emplearon un total de 127 expedientes de escolares de ambos sexos de 16 escuelas primarias públicas en la ciudad de Durango, México. El resto de los expedientes de la muestra del análisis primario fueron excluidos, al no contar con los datos necesarios el análisis. Dichos datos fueron analizados usando SPSS v 15.0. Se analizaron variables sociodemográficas, PA, PGC y frecuencia de consumo semanal de macronutrientes. Resultados: dentro de la población se encontró que existe mayor frecuencia de consumo de grasas (53%). El 2,9% presenta cifras para hipertensión arterial y 3,4% prehipertensión arterial. Existe sobrepeso y obesidad en el 11% y el 19%, respectivamente. Conclusiones: no se encontró influencia del consumo de macronutrientes y el PGC (p= 0,12). Se encontró influencia entre PGC y presión sistólica (25,3%) y diastólica (23,4%).
Abstract:
To assess macronutrients use (MU) influence on body fat rate (BFR) and BFR influence on blood pressure (BP). Methods: A secondary analysis using a correlational descriptive design was performed. Reports from 127 school-age boys and girls from 16 public primary schools in Durango, Mexico, were used. The remaining reports in primary analysis sample were excluded because of missing data. All analyses were performed with SPSS v 15.0 software. Socio-demographic variables, BP, BFR, and weekly intake of macronutrients were evaluated. Results: A higher frequency of fat intake was found among sampled population (53%). Hypertension was found in 2.9% and pre-hypertension in 3.4%. Overweight and obesity were present in 11% and 19% of participants, respectively. Conclusions: No influence from macronutrients use or BFR was found (p = .12). A relationship between BFR and systolic (p = .000) and diastolic blood pressure (p = .000) was observed.

BACKGROUND: Obesity has been generally diagnosed by 'Body Mass Index (BMI)' in primary care. Recently the use of Bioelectrical Impedance Analyzer' has become popular in Korea to evaluate body fat rate (BFR), as cost is inexpensive and the method to use is simple. As a result, the opposed finding of normal BMI and elevated BFR vice versa in same individuals are being encountered frequently. We designed this study to find out the characteristics and cardiovascular risk of people in these groups. METHODS: The medical records of health promotion center were obtained and 22,704 applicants visitor who undeerwent health risk questionnaire, screening tests and physical examination for cardiovascular disease were reviewed. RESULTS: After adjusting for age, sex, exercise and education level, cardiovascular risk such as hypertension, DM, and hypercholesterolemia, LDL tended to increase linearly and HDL tended to decrease linearly with increase of BFR or BMI. In comparison with normal BMI and BFR group, the odds ratios of normal BMI and elevated BFR group or vice versa were increased. CONCLUSION: If either one of BMI or BFR of a person was elevated, even though the other was within normal range, the cardiovascular risk of that person was shown to be high.
