Abstract

IntroductionThe elderly have a greater risk of zinc deficiency compared to younger adults. This condition may be reflected by a lowered zinc intake and reduced zinc absorption in the elderly. The aim of the study was to explore the dietary zinc intake and zinc status differences between male and female elderly.MethodsA cross-sectional study was conducted included eighty-nine free-living subjects, aged above 60 years, apparently healthy and ambulatory. A two day and non consecutive diet record was used to assess energy and nutrient intake of the elderly. It was combined with a semi-quantitative food frequency questionnaire (SQ-FFQ), with food model that was also used to quantify the food pattern on each food frequency item. Serum zinc concentrations were measured by using atomic absorption spectrum photometry. ResultsThe total energy intake and normal serum zinc concentration in both genders of free-living elderly were mostly below the recommended dietary allowance. The mean serum zinc concentration did not differ significantly between female (13.7 µmo/l) and male elderly (13.9 µmo/l). Mostly the intake of zinc was below two thirds of the RDA it presented on intake of zinc in males was much less compared to female. Overall, the prevalence of zinc deficiency appeared low among the free-living elderly in South Jakarta.ConclusionsThe prevalence of zinc deficiency was relatively low in healthy elderly. Prevalence of zinc deficiency and zinc intake were lower in female compared to male elderly.

Abstract

Latar BelakangJumlah populasi dan umur harapan hidup lanjut usia (lansia) semakin meningkat akibat perbaikan dari pelayanan kesehatan masyarakat dan intervensi kedokteran. Dengan semakin meningkatnya umur harapan hidup, maka sangat penting untuk memperbaiki kualitas hidup lansia. World Health Organization (WHO) telah mengembangkan sebuah instrumen untuk mengukur kualitas hidup seseorang yaitu WHO Quality of Life -BREF (WHOQOL-BREF). WHOQOL-BREF terdiri dari empat domain yaitu fisik, psikologik, sosial dan lingkungan. Penelitian ini bertujuan untuk menilai validitas dan reliabilitas dari WHOQOL-BREF sebagai instrumen untuk mengukur kualitas hidup lansia. MetodeSebuah rancangan potong silang dilakukan di Kecamatan Mampang, Jakarta Selatan. Selama dua bulan (Oktober dan November 2005) sebanyak 306 lansia (usia ³60 tahun, mampu berjalan, mampu berkomunikasi, dan tidak dalam kedaan terminal) bersedia ikut serta dalam penelitian. Sepuluh pewancara yang sudah dilatih mengumpulkan informasi tentang umur, jenis kelamin, pendidikan, status pernikahan, dan kualitas hidup. HasilHasil penelitian menunjukkan distribusi skor setiap domain dari WHOQOL-BREF adalah simetris dan tidak didapatkan efek floor atau ceiling. Validitas diskriminan, validitas konstruk, dan konsistensi internal menunjukkan hasil yang baik dari skor keempat domain. Namun terdapat dua item pertanyaan yaitu tentang perasaan negatif dan kepuasan hidup seksual yang menunjukkan korelasi yang lemah dengan domain psikologik dan sosial. Kedua pertanyaan ini harus dimodifikasi supaya lebih mudah dipahami oleh lansia. KesimpulanWHOQOL-BREF merupakan instrumen yang valid dan reliable untuk mengukur kualitas hidup lansia, tetapi masih diperlukan sedikit perbaikan.

Abstract

Background One of the extra-skeletal roles of vitamin D for health is associated with cardiovascular disease. Poor vitamin D status has been associated with vascular endothelial dysfunction. There were controversial results about the association between vitamin D deficiency and matrix metalloproteinase 9 (MMP-9) concentration. The purpose of the present study was to determine the concentrations of 25(OH) vitamin D [25(OH)D] in an elderly population and to find any association between 25(OH)D and MMP-9 concentrations.MethodsThis study was of cross-sectional design involving 160 male and female subjects aged 55–65 years, in South Jakarta, Indonesia. Determination of MMP-9 and 25(OH)D concentrations was done concurrently on subjects who met the inclusion and exclusion criteria after all study subjects had been selected. 25(OH)D and MMP-9 concentrations were assessed by direct competitive chemiluminescence immunoassay (CLIA) and enzyme-linked immunosorbent assay (ELISA) respectively. Statistical analysis used chi square and t tests.ResultsMean 25(OH)D concentration in the study subjects was 14.4 ± 6.4 ng/mL. A total of 68.8% of subjects had a 25(OH)D level of <20 ng/mL, and 31.2 % had a 25(OH)D level of >20 ng/mL.There was an increased MMP-9 concentration in male subjects with a 25(OH)D level of <20 ng/mL compared with subjects with 25(OH)D level of >20 ng/mL (p=0.011), but not among female subjects (p=0.809).ConclusionThe MMP-9 concentration was increased among male subjects with low level of (OH)D. This study confirmed that 25(OH)D concentration may have a potential role in endothelial function.

Abstract

Background Sleep is needed by the human body so that the performance of body remains optimal when the body is awake, especially during work. Informal workers often work without clear regulations, with inadequate equipment and poor work environment, and pay little attention to occupational health and safety factors. The existence of large work demands with unclear work system arrangements will certainly result in a mental workload in these workers. The objective of this study was to determine the relationship between mental workload and sleep patterns of workers in the informal garment sector. MethodsA cross-sectional study involving 225 informal garment workers was conducted between December 2018 and May 2019. Data collection included respondents’ demographics, job characteristics, measurement of mental burden and disturbances in sleep patterns. The sleep pattern used the PSQI (Pittsburgh Sleep Quality Index) instrument and the mental burden used the Rating Scale Mental Effort (RSME). A multiple linear regression analysis was used to analyze the data. ResultsThe mean sleep quality was 5.40 ± 2.54. Multiple linear regression test found that mental workload correlated significantly with sleep quality of workers (β=0.016, p=0.012).ConclusionThis study demonstrated that heavy mental workload decreases the quality of sleep in informal garment workers. A good work system management is required so that workers are assigned that portion of the task that is commensurate with their capacity.
