Different Amounts of Physical Activity Measured by Pedometer and the Associations With Health Outcomes in Adults

Alessandra Madia Mantovani, Scott Duncan, Jamile Sanches Codogno, Manoel Carlos Spiguel Lima, and Rômulo Araújo Fernandes


Physical activity level is an important tool to identify individuals predisposed to developing chronic diseases, which represent a major concern worldwide.


To identify correlates of daily step counts measured using pedometers, as well as analyze the associations between health outcomes and 3 different amounts of daily physical activity.


The sample comprised 278 participants (126 men and 153 women) with a mean age of 46.51 ± 9.02 years. Physical activity was assessed using pedometers for 7 consecutive days, and 3 amounts of daily physical activity were considered: ≥10,000 steps/day, ≥7500 steps/day, and <5000 steps/day. Sleep quality was assessed through a questionnaire, and dual-energy x-ray absorptiometry was used to measure body fat. Sociodemographic and anthropometric data were also collected.


The percentages of adults achieving at least 10,000 and 7500 steps/day on a minimum of 5 days of the evaluated week were 12.9% and 30.9%, respectively. Adults who reached ≥7500 steps/day had a lower likelihood of being obese (odds ratio [OR] = 0.38, 95% confidence interval [CI], 0.17–0.85) and reporting worse sleep quality (OR = 0.58, 95% CI, 0.34–0.99). Adults who reached <5000 steps/day had a higher likelihood of reporting worse sleep quality (OR = 2.11, 95% CI, 1.17–3.82).


Physical activity in adulthood, as measured by pedometer, constituted a behavior related to lower adiposity and better sleep quality.

Objectively Measured Physical Activity and Healthcare Expenditures Related to Arterial Hypertension and Diabetes Mellitus in Older Adults: SABE Study

Denise Rodrigues Bueno, Maria de Fátima Nunes Marucci, Clara Suemi da Costa Rosa, Rômulo Araújo Fernandes, Yeda Aparecida de Oliveira Duarte, and Maria Lucia Lebão

Research using questionnaires has shown that physical activity level (PAL) is associated with healthcare costs. The purpose of this study was to examine the association between objectively measured PAL and healthcare costs among hypertensive and diabetic noninstitutionalized Brazilian older people. The method consisted of a cross-sectional study forming part of the SABE Study, composed of 377 older people interviewed in 2010. Expenditures were estimated taking into account self-reported medicine prescription, outpatient service, and hospitalizations, with the highest quartile of expenditures considered as a risk category. PAL was estimated using an Actigraph accelerometer. Associations were expressed as odds ratios and 95% confidence intervals, adjusted for covariates. Overall expenditures were higher in the sedentary group. The insufficiently active group presented greater odds for higher total, outpatient, and hospitalization expenditure. It was concluded that healthcare expenditures were lower in more active hypertensive and diabetic older people. The promotion of physical activity could be relevant in the attenuation of the burden of chronic diseases in economic losses.

Association of TV Viewing and All-Cause Mortality in Older Adults With Hypertension: A 6-Year Longitudinal Study

Ítalo Ribeiro Lemes, Xuemei Sui, Bruna Camilo Turi-Lynch, Steven N. Blair, Rômulo Araújo Fernandes, Jamile Sanches Codogno, and Henrique Luiz Monteiro

The purpose of this study was to examine the longitudinal association between television (TV) viewing and all-cause mortality in older adults with hypertension. Sedentary behavior, physical activity, hypertension, and other chronic diseases were assessed by face-to-face interviews and confirmed by medical history. Mortality was reported by relatives and confirmed in medical records of the National Health System. The fully adjusted model showed a direct association between high TV viewing time and all-cause mortality; hazard ratio: 1.65 (95% confidence interval [1.02–2.68]). Women with high TV viewing were more likely to die than men. Higher TV viewing time was associated with all-cause mortality among those with diabetes and hypertension; hazard ratio: 3.54 (95% confidence interval [1.64–7.66]). The findings from this longitudinal study show that higher TV viewing time is associated with higher risk for all-cause mortality among older adults with hypertension, independently of physical activity, and other potential confounders.

Adults Engaged in Sports in Early Life Have Higher Bone Mass Than Their Inactive Peers

Alessandra Madia Mantovani, Manoel Carlos Spiguel de Lima, Luis Alberto Gobbo, Enio Ricardo Vaz Ronque, Marcelo Romanzini, Bruna Camilo Turi-Lynch, Jamile Sanches Codogno, and Rômulo Araújo Fernandes

Purpose: To analyze the relationship between engagement in sports in early life and bone variables among adults of both sexes. Methods: The sample was composed of 225 men and women. Demographic data were collected, and dual-energy X-ray absorptiometry was used to assess bone mineral density, bone mineral content, and lean soft tissue. Sports participation in early life was assessed by an interview including childhood and adolescence. Consumption of tobacco and alcohol was also assessed by interview and the habitual physical activity level by a pedometer. Results: Inactive men had bone mineral content around 11% lower than active men in childhood or adolescence, whereas for women, this difference represented around 14%. Active men had 74% less fat mass than inactive men in early life, and the difference was 67% for women. Early sports participation explained the differences in whole-body bone mineral content (16.8%, P-value = .005) and bone mineral density (8.8%, P-value = .015), as well as bone mineral density in lower limbs (18.9%, P-value = .001) among women. Conclusion: Adults engaged in sports in early life have higher bone mass than their inactive peers, especially women.
