Objective

To determine the relationship between nutritional intake and physical activity with bone resorption of Indonesian elderly

Place

Malang, East Java

Method

A cross-sectional study in 109 community dwelling elderly (>60 y) free of medication know to affect bone. Semiquantitative FFQ, validated with 1x24 hour food recall was used to assess energy, protein, calcium, and vitamin D. Assessment of physical activity was done with a questionnaire based on the Dutch questionnaire modified by Josten. Bone resorption were measured by its collagen degradation product, C-telopeptide in serum. Bivariate and multivariate analysis was done to assess relationship between nutrients and physical activity with biomarker of bone resorption.

Results

Subject were 49 men and 60 women with mean age of 68,19 +/- 5,91 years old. Most subject had moderate high education, and a middle low income. Based on the Physical Acticity Index, most subjects has moderate to highphysical activity. The body mass index of most subjects were normal to obese. Mean intake of energy in subjects were 1548 +/- 416,23 kcal. Mean intake of protein were 59,14 +/- 11,37 g/d, mean Calcium intake were 928,62 mg/d and mean vitamin D intake were 9,85 +/- 5,09 µg. There were significant negative correlation between intakes of energy, protein, calcium, and physical activity with CTx. Significant negative correlation were also found between intakes of energy, protein, calcium with calcium creatinine ratio, while positive significant correlation were found with age. Multiple regression analysis showed significant relationship between protein and calcium intakes and physical activity with CTx and between calcium intake and age with calcium creatinine ratio.

Conclusion

Mean intake of energy were lower than the Indonesian RDA. But at this level BMI were normal to obese. Mean intakes of protein, calcium and vitamin D were well above the Indonesian RDA. Significant relationship were found between intakes of protein and calcium and physical activity with bone resorption. The rather low but statistically significant relationship, shows that the other factors in food sources, that may play role in bone resorption, such as osteoprotegerin/OPG, IGF-1, potassium, vitamin K, zinc and magnesium."

"Latar Belakang. Densitas tulang yang rendah pada usia lanjut antara lain dipengaruhi oleh gangguan produksi dan metabolisme vitamin D, konsumsi alkohol, aktivitas fisik yang kurang, indeks massa tubuh (IMT) yang rendah, merokok yang berlebihan dan asupan kaisium yang rendah.

Backgrounds

Low bone density in elderly may be caused by decreased production and metabolic dysfunction of vitamin D metabolism, alcohol consumption, decreased physical activity, low BMI, excessive smoking, and low calcium intake. Calcium intake, BMI and physical capacity had already been known to have influence on BMD. The correlation between calcium intake, BMI and physical capacity with BMD is still controversial and there is not much data in Indonesia regarding of it especially in elderly population.

Objective

To investigate the correlation between calcium intakes, body mass index and physical capacity with lumbar and femoral bone mass density of elderly women in nursing homes.

Methods

A cross sectional study was conducted in elderly women in nursing homes. Subjects were obtained by cluster random sampling method and fulfilled inclusion criteria Inclusion criteria were age more than 60 years old, female, and Barthel index >16. We have done Pearson correlation test with Spearman test as alternative if data distribution was not normal.

Result

A cross sectional study was conducted on 51 elderly women in 2 nursing homes in Bekasi between March and May 2005. Median age was 70.5 years, median calcium intake 283 gram/day, BMI 22.28 ± 42 kg/m2 and physical capacity 4.8 ± 1,6 metz. Mean of lumbar BMD was 0.842 ± 0.164 gram/cm2 and mean femoral BMD was 0.652 ± 0.097 gram/cm2. We found significant correlation between BMI and lumbar and femoral BMD (r).677;p).000 and r =508; p=0.000) and there was no correlation between calcium intake and lumbar and femoral BMD (rO.146;p-0.000 and r=0.096;p=0.50 l ). There were no correlation found between physical capacity and lumbar and femoral BMD (r).016;p 0.913 and r-0.143 and p O.318).

Conclusion

This study showed correlation between BMI and lumbar and femoral BMD. We found no correlation between calcium intake and physical capacity with femoral and lumbar BMD in elderly women in nursing homes in Jakarta and Bekasi. Prevalensi of lumbar BMD and femoral BMD of elderly women in nursing homes in Jakarta was decreased (100% and 99,8%).Calcium intake was low, BMI was normal and physical capacity was moderate level."

"ABSTRAKLatar belakang: Kerusakan oksidatif berperan dalam proses penuaan dan juga beberapa penyakit degeneratif. Menjaga status antioksidan tubuh merupakan hal penting dalam mencegah terjadinya kerusakan oksidatif. Selenium adalah mineral yang penting mengingat perannya dalam pembentukan enzim antioksidan (selenoprotein), salah satunya glutation peroksidase untuk perlindungan terhadap radikal bebas. Tujuan penelitian ini adalah untuk mempelajari hubungan antara asupan selenium dan aktivitas glutation peroksidase dengan karbonil plasma pada usia lanjut. Metode Penelitian: Penelitian potong lintang ini dilakukan di 5 Posbindu di Jakarta Selatan. Dilakukan wawancara untuk mengetahui identitas dan riwayat penyakit kronis. Data aktivitas fisik didapat melalui wawancara dengan kuesioner Physical Activity Scale for the Elderly (PASE). Indeks massa tubuh diperoleh dari hasil pemeriksaan antropometri berupa berat badan dan tinggi badan dari konversi tinggi lutut. Data asupan makan subjek diperoleh dari wawancara food recall 24 jam pada satu hari kerja dan satu hari libur serta Semi Quantitative-Food Frequency Questionnaire (SQ-FFQ). Pemeriksaan laboratorium dilakukan di laboratorium biokimia FKUI untuk mengetahui aktivitas glutation peroksidase, dan karbonil plasma. Hasil: Sebanyak 94 usia lanjut dengan rerata usia 70,34 ± 6,079 tahun mengikuti penelitian ini. Sebanyak 40% subjek mempunyai status gizi normal dengan 69,1% subjek memiliki riwayat penyakit kronis. Sebanyak 75,5% subjek pada penelitian ini belum mencukupi kebutuhan asupan selenium yang direkomendasikan Rerata kadar karbonil plasma 5,83 ± 1,95 nmol/ml dan 69,1% subjek mempunyai aktivitas glutation peroksidase yang rendah.. Hasil analisis statistik menunjukkan tidak terdapat korelasi antara asupan selenium dengan aktivitas glutation peroksidase. Pada analisis multivariat asupan selenium dan tiga variabel perancu yaitu usia, indeks massa tubuh, dan asupan beta karoten hanya mempengaruhi kadar karbonil plasma sebanyak 3,7%. Diskusi: Hasil asupan selenium pada penelitian ini jauh lebih rendah dibandingkan dengan hasil penelitian sebelumnya. Makanan sumber selenium banyak berasal dari makanan berprotein yang dikonsumsi sehari-hari sehingga data asupan selenium didapat dari gabungan antara food recall 2 x 24 jam dan SQ-FFQ. Pemeriksaan status kognitif subjek juga perlu dilakukan untuk memastikan ada tidaknya gangguan kognitif. Pemeriksaan status antioksidan endogen lain seperti glutation (GSH) juga perlu dilakukan pada penelitian berikutnya untuk mengetahui faktor lain yang mempengaruhi aktivitas glutation peroksidase dalam menekan kerusakan oksidatif pada usia lanjut.

ABSTRACTIntroduction: Oxidative stress contributed in aging process and several degenerative diseases. Maintaining the body's antioxidants status were important to prevent oxidative stress. Selenium was an important trace element due to as a component of antioxidants enzymes (selenoproteins), including glutathione peroxidase for protection against free radical. We aimed to study the association between selenium intake and glutathione peroxidase activity with plasma carbonyl in elderly. Methods: Cross sectional study was held in 5 elderly communities in south Jakarta. Identity and chronic disease history were obtained from interview and Physical activity scale for the elderly (PASE) questionnaire used for assess physical activity. Weight and knee height measurement used to determine body mass index. Dietary intake data obtained from repeated 24 hours recall and Semi Quantitative-Food Frequency Questionnaire (SQ-FFQ). laboratory examination held in laboratory of biochemistry FKUI for assess glutathione peroxidase activity and plasma carbonyl level. Results: There were 94 elderly with mean of age 70.34 ± 6.079 years old contributed to this study. 40 % subjects had normal nutritional status and 69.1 % subject had history of chronic disease. There were 75.5 % subject had low intake of selenium. Mean of plasma carbonyl was 5.83 ±1.95 nmol/ml and 69.1% subject had low glutathione peroxidase activity. Statistical analysis results showed there were no significant correlation between selenium intake and glutathione peroxidase. In multivariate analysis selenium intake, age, body mass index, and beta-carotene intake explained 3,7% of the plasma carbonyl. Discussion: The result of selenium intake in current study much lower than previous study. Dietary selenium data obtained from repeated 24 hours recall combine with FFQ-SQ because the selenium food source similar with protein foods that consume daily. Assessment of cognitive function among subject needed for ensure cognitive status related to ability to remember dietary intake. Status of endogen antioxidant including glutathione (GSH) need to be considered for understanding about another factor that influence glutathione peroxidase in preventing oxidative stress."

Objective: A reduction in the number of posterior teeth is associated with diminished nutrition intake, nutritional status, and masticatory performance in the elderly. Previous studies on the relationships between tooth loss, nutrition intake, nutritional status, and masticatory performance have yield varying results. Methods: A total of 158 subjects aged 60 years and older from Depok, West Java, Indonesia were enrolled in the study. Posterior tooth contacts were assessed based, and the subjects were accordingly divided into two groups based on the Eichner Index; group A2-B3 and group B4-C3. A semi-quantitative food-frequency questionnaire was used to measure nutritional intake in the form of total calories, and the Mini-Nutritional Assessment-Short Form was used to measure nutritional status. Results: Seventy-four percent of participants were females, and the remaining (26%) were males. A significant difference in the mean masticatory performance score (p = 0.000) was noted between Eichner group A2-B3 (5.66 ± 1.80) and B4-C3 (3.20 ± 1.25). However, no statistically significant differences in nutritional status and calorie intake were noted between the two groups. Conclusion: These findings indicate that the number of teeth lost is related to mastication, but not to nutritional status or calorie intake in the elderly."
