Abstrak: Evidence for a relation between physical activity and renal cell cancer has been inconsistent. The authors examined physical activity in relation to renal cell cancer in a large, prospective US cohort study of 482,386 participants (289,503 men and 192,883 women) aged 50–71 years at baseline (1995–1996). At baseline, participants reported their frequency of exercise of at least 20 minutes' duration, intensity of daily routine activity, and frequency of physical activity during adolescence. During 8.2 years of follow-up (through December 2003), 1,238 cases of renal cell cancer were ascertained. In multivariate Cox regression models adjusted for renal cell cancer risk factors, the authors observed that current exercise, routine physical activity, and activity during adolescence were associated with a reduced risk of renal cell cancer. The multivariate relative risks for the highest activity level as compared with the lowest were 0.77 (95% confidence interval (CI): 0.64, 0.92; ptrend = 0.10) for current exercise, 0.84 (95% CI: 0.57, 1.22; ptrend = 0.03) for routine physical activity, and 0.82 (95% CI: 0.68, 1.00; ptrend = 0.05) for activity during adolescence. The authors conclude that increased physical activity, including activity during adolescence, is associated with reduced risk of renal cell cancer.

Abstrak: This observational study examined the associations of built environment features around the home and workplace with cardiorespiratory fitness (CRF) based on a treadmill test and body mass index (BMI) (weight (kg)/height (m)²). The study included 8,857 adults aged 20–88 years who completed a preventive medical examination in 2000–2007 while living in 12 Texas counties. Analyses examining workplace neighborhood characteristics included a subset of 4,734 participants. Built environment variables were derived around addresses by using geographic information systems. Models were adjusted for individual-level and census block group–level demographics and socioeconomic status, smoking, BMI (in CRF models), and all other home or workplace built environment variables. CRF was associated with higher intersection density, higher number of private exercise facilities around the home and workplace, larger area of vegetation around the home, and shorter distance to the closest city center. Aside from vegetation, these same built environment features around the home were also associated with BMI. Participants who lived and worked in neighborhoods in the lowest tertiles for intersection density and the number of private exercise facilities had lower CRF and higher BMI values than participants who lived and worked in higher tertiles for these variables. This study contributes new evidence to suggest that built environment features around homes and workplaces may affect health.

Abstrak:

Persalinan merupakan hal yang menyenangkan sekaligus menakutkan bagi ibu karena sarat dengan risiko terjadinya morbiditas dan mortalitas, salah satu penyebabya adalah persalinan lama. Oleh karenanya perlu persiapan fisik dan mental ibu yang salah satu  caranya melalui senam hamil. Penelitian ini untuk mengetahui hubungan senam hamil dan  persalinan lama di RSPAD Gatot Soebroto dari Desember 2009 – Desember 2010. Studi ini menggunakan desain kasus kontrol demgan 117 kasus persalinan lama dan 117 kontrol. Data diperoleh dari catatan medik, Analisis data dengan Regresi logistik. Ibu yang  tidak melakukan senam hamil akan berisiko mengalami kejadian persalinan lama 7.9 kali dibandingkan ibu yang mengikuti senam hamil setelah dikontrol variabel tinggi badan dan paritas. Faktor determinan persalinan lama adalah tidak senam hamil, berat badan lahir lebih dari 3500 gram, tinggi badan kurang dari 150 cm dan paritas sama dengan satu. Mengenalkan dan memberikan penyuluhan pada setiap ibu hamil yang melakukan pemeriksaan antenatal tentang manfaat senam hamil serta memotivasi ibu untuk mengikuti kegiatan senam hamil. Daftar Bacaan : 58(1998 – 2010) Kata Kunci : Persalinan lama, Senam hamil.

Due to the risk of morbidity and mortality caused by prolonged labor, labor is both exciting and frightening to mothers. Therefore, physical dan mental preparation are needed. One of the ways is by doing pregnancy exercise.  This study wants to know the relation between pregnancy exercise and prolonged labor in Gatot Soebroto Hospital during December 2009 – December 2010. Method. This study used case design control with 117 prolonged labor and 117 control. The data was taken from medical record, data analysis and logistic regression. Result. Mothers refused taking pregnancy exercise has the chance of 7.9 times having prolonged labor compared to mothers who applied it. The result was taken after controlled by height and parity. Prolonged labor is determined by pregnancy exercise, birth height and weight, and parity. Suggestions. Introduce and give healthcare education to pregnant mothers during ANC. Mothers should also be motivated to take pregnancy exercise and the advantages. References : 58(1998 – 2010) Key words : Prolonged labor, pregnancy exercise.

Abstrak: Unhealthy lifestyle habits are a major contributor to coronary artery disease. The purpose of the present study was to investigate the associations of smoking, weight maintenance, physical activity, and diet with coronary calcium, cardiovascular events, and mortality. US participants who were 44-84 years of age (n = 6,229) were followed in the Multi-Ethnic Study of Atherosclerosis from 2000 to 2010. A lifestyle score ranging from 0 to 4 was created using diet, exercise, body mass index, and smoking status. Coronary calcium was measured at baseline and a mean of 3.1 (standard deviation, 1.3) years later to assess calcium progression. Participants who experienced coronary events or died were followed for a median of 7.6 (standard deviation, 1.5) years. Participants with lifestyle scores of 1, 2, 3, and 4 were found to have mean adjusted annual calcium progressions that were 3.5 (95% confidence interval (CI): 0.0, 7.0), 4.2 (95% CI: 0.6, 7.9), 6.8 (95% CI: 2.0, 11.5), and 11.1 (95% CI: 2.2, 20.1) points per year slower, respectively, relative to the reference group (P = 0.003). Unadjusted hazard ratios for death by lifestyle score were as follows: for a score of 1, the hazard ratio was 0.79 (95% CI: 0.61, 1.03); for a score of 2, the hazard ratio was 0.61 (95% CI: 0.46, 0.81); for a score of 3, the hazard ratio was 0.49 (95% CI: 0.32, 0.75); and for a score of 4, the hazard ratio was 0.19 (95% CI: 0.05, 0.75) (P < 0.001 by log-rank test). In conclusion, a combination of regular exercise, healthy diet, smoking avoidance, and weight maintenance was associated with lower coronary calcium incidence, slower calcium progression, and lower all-cause mortality over 7.6 years.
