Abstract

Background: Food safety is defined as the confidence level that food will not cause sickness or harm to consumer when it is prepared, served, and eaten according to its intended use. This study was conducted to describe the pattern of knowledge, attitude, and practice on food safety among high school students in Jatinangor.Methods: One hundred and two respondents were involved in this study. The data were collected from the high school students in Jatinangor, West Java from August to November 2013 through the methods of questionnaire after the informed consent was obtained from the respondents. The questionnaire was translated from the Five Keys to Safer Food Manual by World Health Organization. The collected data were then presented in percentage.Results: Overall, 60.78% of respondents had moderate knowledge, 85.29% had good attitude, and 71.57% had good practice in food safety. Among the five main points on food safety in all aspects, most of the respondents were unaware of the safe temperature to store food; hence, they did not practice it.Conclusions: Even though most of the students have the knowledge, attitude, and practice on food safety, a need for relevant and motivating education should be performed for spesific indicators of food safety. [AMJ.2016;3(2):206–11]DOI: 10.15850/amj.v3n2.797

Abstract

Background: Knee osteoarthritis (OA) is a degenerative disease of the knee joints characterized by progressive softening and disintegration of articular cartilage. In OA, which is influenced by several risk factors, free radicals are increased by local ischemia in the cartilage. As an exogenous antioxidant, vitamin C also plays an important role in collagen and glycosaminoglycan synthesis. This study was carried out to identify vitamin C intake as well as risk factors in knee OA. Methods: The study population was determined by non-probability sampling with convenient approach to knee OA patients at the Rheumatology Outpatient Clinic of Dr. Hasan Sadikin General Hospital in October–November 2013. Data were obtained through questionnaire interview about risk factors, severity index of OA and vitamin C intake profile. Data presentation was conducted by descriptive method.Results: There were 47 patients diagnosed with knee OA in the Rheumatology Outpatient Clinic. The result showed that 7 patients (14.9%) had low vitamin C intake for the last 3 months. There were 30 patients with family history of OA (63.8%). Thirty two patients (68.1%) were passive smokers, 44 patients (93.6%) had history of repeated use of knee joints and majority of respondents had obesity.  Conclusions: Most of the subjects have sufficient vitamin C intake and more than half have risk factors that may contribute to the incidence of knee OA. DOI: 10.15850/amj.v4n2.1067

Abstract

Background: Studies have shown that muscle strength will decline with aging and inactivity, with 1% to 3% loss of muscle strength each day. Nevertheless, different lifestyles have different effect on muscle strength. This study was conducted to analyze the differences in quadriceps and hamstring muscle strength in elderly from 60–79 years olds according to lifestyle.Methods: A cross-sectional study was conducted from September to November 2015. The subjects were 31 older persons from community who voluntarily participated the research procedure and were divided into 2 groups, active group and sedentary group according to International Physical Activity Questionnaire (IPAQ). Quadriceps and hamstring muscle strengths were measured using the push and pull dynamometer. The collected data were analyzed using the Wilcoxon rank sum test and the unpaired t-test. Results: This study discovered that the mean difference in hamstring muscle strength was 6.09 ± 0.70, p< 0.001; median difference in Quadriceps muscle strength was 5.00 (13.00, 6.50), p<0.001. Conclusions: There is a higher Quadriceps and Hamstring muscle strength in elderly active lifestyle compared to elderly sedentary lifestyle.
