The Impact

Background: Obesity is increasingly prevalent in the industrialized world. Obese workers have two times the number of workers’ compensation claims as those of non-obese workers. Worksite interventions may be especially effective because employees spend a large part of their day in the work environment, and both employee and employer have incentives to improve the employees’ health.Objective: To assess the impact of a 4 week employee intervention in participant’s weight, body fat and blood pressure.Methods: This was a pilot study. We assessed feasibility and impact compared to baseline at 4 weeks, 6 months, and 12 months post-program. The primary outcomes were weight and body mass index. Secondary outcomes included percent body fat and blood pressure. Results: Forty participants consented to be part of the study. Baseline weight was 97.8 kg [SD ± 17.05]. Twelve months post-intervention weight loss averaged 2.7 kg [SD ± 6.35]. One-way repeated measures ANOVA showed a significant effect of participation on weight, body mass index, and percent body fat.Conclusion: Significant improvements in the primary outcomes were observed in participants completing our worksite pilot study, indicating that a worksite weight loss intervention is potentially effective.International Journal of Occupational Safety and Health, Vol 4 No 2 (2014) 44– 50

The Impact

The incidence and prevalence of nontuberculous mycobacterial pulmonary disease (NTM-PD) have been increasing worldwide. The risk of NTM-PD may be higher in undernourished populations. We tried to elucidate the impact of body mass index (BMI) and its change on development of NTM-PD in this study.We performed a retrospective cohort study including South Koreans age >40 years who underwent biennial National Health Insurance System (NHIS) health checkups in both 2005 and 2009 or 2006 and 2010. We monitored eligible individuals from the study initiation date (NHIS health checkup date on 2009 or 2010) until the diagnosis of NTM-PD or December 31, 2017. Enrolled individuals were classified based on BMI at initiation date. We compared NTM-PD incidence per 100 000 person-years by BMI group as well as by BMI change by calculating hazard ratio (HR).A total of 5 670 229 individuals were included in the final analysis. Compared with the BMI <18.5 kg·m−2 group, the incidence of NTM-PD gradually decreased with increased BMI: adjusted HR (aHR) 0.38 (95% confidence interval [CI] 0.35–0.42) for BMI 18.5–22.9, 0.17 (0.15–0.19) for BMI 23–24.9, 0.1 (0.09–0.11) for BMI 25–29.9, and 0.01 (0.07–0.13) for BMI ≥30. A BMI decrease of ≥1 kg/m2 over 4 years increased the incidence of NTM-PD (aHR 1.08, 95% CI 1.01–1.16) whereas a BMI increase of ≥1 decreased the NTM-PD incidence (0.77, 95% CI 0.71–0.83).In conclusion, BMI was inversely related to development of NTM-PD and weight loss increased the risk of NTM-PD.

Sedentary Women

The aim of this study was to investigate the effects of 12-week regular step aerobic exercises on body fat values of adult sedentary women. 35 female joined to the study voluntarily who work as academic and administrative staff in Isparta Süleyman Demirel University. Step aerobic exercises were applied to the participants regularly as 12 weeks, 3 days a week, 60 minutes a day. The tempo of music in the exercises was based on “Bpm≥120”. Body fat ratios and fat mass measurements were taken with TANITA BC 418 Professional Body Analysis Device. Datas were compared by using “Repeated-Measures ANOVA” at SPSS 18 Statistics Programme. Participants’ mean of age was calculated 35,20±6,26 years and mean of lenght was calculated 168,48±5,09 cm. There were no statistical differences as a result of comparison of pre, mid and post-test weight, body fat ratio, fat mass and body mass index values taken from participants (p>0,05). As a result, according to findings handled from the research and similar studies in the literature, it can be thought that short-term Step-Aerobic exercises can cause reductions in body fat ratio values; but cannot cause reductions in weight and body mass index values because of the increment in muscle mass. Planning long-term exercises can be suggested to the future studies for being seen positive effects in these values. Additionally, for optimum physical fitness, these can be suggested to the participants that they should pay attention to their eating habits and should attend the exercises with a dietician control. ÖzetBu çalışmanın amacı, 12 haftalık düzenli step aerobik egzersizlerinin yetişkin sedanter kadınlarda vücut yağ değerlerine etkisinin incelenmesidir. Araştırmaya Isparta Süleyman Demirel Üniversitesi’nde akademik ve idari personel olarak çalışan 35 kadın gönüllü katıldı.  Katılımcılara düzenli olarak 12 hafta, haftada 3 gün, günde 60 dakika step aerobik egzersizleri uygulandı. Egzersizlerde müzik temposu “Bpm≥120” olarak baz alındı. Vücut yağ yüzdesi ve yağ kütlesi ölçümleri TANİTA BC 418 Profesyonel Vücut Analiz Cihazı ile alındı. Veriler SPSS 18.0 programında “Repeated-Measures ANOVA” kullanılarak analiz edildi. Katılımcıların yaş ortalaması 35,20±6,26 yıl ve boy ortalaması 168,48±5,09 cm olarak hesaplandı.  Katılımcılardan alınan vücut ağırlığı, vücut yağ yüzdesi, yağ kütlesi ve beden kütle endeksi ön, ara, son test değerlerinin karşılaştırılması sonucunda istatistiksel olarak farka rastlanmadı (p>0,05). Sonuç olarak, araştırmada ve literatürdeki benzer çalışmalardan elde edilen bulgulara göre, kısa dönem Step-Aerobik egzersizlerinin vücut yağ yüzdesi değerlerinde azalmaya neden olabileceği; fakat vücut ağırlığı ve beden kütle endeksi değerlerinde azalmaya neden olmamasının kas kütlesindeki artıştan dolayı olduğu düşünülmektedir. İleride yapılacak araştırmalarda bu değerlerde pozitif etkilerin görülebilmesi için daha uzun süreli egzersizlerin planlanması önerilebilir. Ek olarak, optimum fiziksel uygunluk için planlanan egzersizlerin yanı sıra katılımcılara bu tip egzersizlerde beslenme alışkanlıklarına dikkat etmeleri ve bir diyetisyen kontrolünde egzersizlere katılmaları önerilebilir.

Significant Difference

Background: Body mass index (BMI) is frequently labeled as “flawed” in assessing obesity since it cannot differentiate between muscle and fat leading to misclassifications of healthy individuals. Bioelectrical impedance analysis (BIA) may be a more accurate indicator of obesity since it can distinguish the difference between muscle and fat in children. This pilot study investigated discrepancies between BMI and BIA body composition classifications in children with high levels of physical activity.Methods: Participants were selected from three elementary schools (N = 380, K = 76, 1st = 64, 2nd = 62, 3rd = 61, 4th = 83, and 5th = 34) receiving 60 min of outdoor, unstructured play daily. BIA scales were used to collect each child's body fat percentage and BMI score, then those numbers were categorized by BIA and BMI normative values as either underweight, healthy, overweight, or obese.Results: Overall, 26% of the students were classified differently when using the normative classifications for BMI and BIA, with the largest discrepancy found in the overweight category at 38%. Similar inconsistencies were found when students were divided as younger (42%) vs older students (36%), and males (40%) vs. females (35%).Conclusions: This pilot study demonstrated that there is a significant difference in how BMI and BIA discriminate between the different body composition categories. BIA consistently shows to be a more accurate tool in assessing obesity rates in children since it directly measures body fat.

Spirulina, a cyanobacteria commonly referred to as a blue-green algae, is one of the oldest lifeforms on Earth. Spirulina grows in both fresh and saltwater sources and is known for its high protein and micronutrient content. This review paper will cover the effects of spirulina on weight loss and blood lipids. The currently literature supports the benefits of spirulina for reducing body fat, waist circumference, body mass index and appetite and shows that spirulina has significant benefits for improving blood lipids.

The Impact

1. The impact of frame-size categories in weight-height tables was studied by comparing the efficiency of the body-mass index (weight/height2 (W/H2)) and weight adjusted for body-height and a body-diameter, W/(H2Dp), in predicting body fatness.2. Body-weight, body-height, six body-diameters and four skinfold thicknesses were measured in ninety-five men and seventy women, aged between 23 and 35 years. Percentage of body fat was calculated from skinfold thicknesses using regression equations according to Durnin & Womersley (1974).3. The inclusion of a body-diameter increased the explained variation of body fatness from 57% to 62% (knee) and 63% (shoulder) in men and from 63% to 69% (knee) in women.4. It can be concluded that in the present population the efficiency of the prediction of percentage of body fat was not improved markedly by the inclusion of a body-diameter in the body-mass index, thus giving no support for the inclusion of frame-size categories in weight-height tables.
