“…These dependent variable scores showed a strong skewness because of a long right-hand tail. Therefore, consistent with similar studies (De Backer et al, 1981;Folsom etal., 1991), alogarithmic transformation was used to approximate to the normal distribution.…”

“…A modified Dutch version of the Minnesota Leisure Time Physical Activity (LTPA) Questionnaire and the structured interview validated by Taylor et al (1978), developed for the Belgian Physical Fitness Study (De Backer et al, 1981), was used to obtain information on daily LTPA over a T-year period. Activities were classified by their energy requirements as low (up to 3.5 kcal/min), moderate (4 to 6 kcal/min), and vigorous (more than 6 kcal/min) physical activities.…”

Tracking and explaining physical activity in young adults was investigated in a 7-year longitudinal design. From a representative sample of 980 respondents at baseline (M age = 21 years), 172 respondents, comprising 18% of the original sample, completed psychosocial questionnaires and were interviewed at home to assess their level of physical activity at follow-up. Psychosocial variables were grouped into four groups: social variables, self-efficacy, perceived benefits, and perceived barriers. Drop-out analyses showed no major differences between the baseline and follow-up samples. The aims of the present study were: (a) to investigate tracking in physical activity and psychosocial determinants over a 7-year period, and (b) to examine baseline determinants and change in determinants in predicting physical activity change in men and women. No significant tracking of physical activity level was found for men. For women, moderate tracking scores were found for total energy expenditure and moderate-intensity energy expenditure (r = .34 and .41, respectively). There was higher tracking in psychosocial determinants than in physical activity. Relatively high tracking scores for perceived benefits and barriers suggest that cognitions related to physical activity are more stable than the behavior itself. Although baseline psychosocial variables were poor predictors of physical activity change, determinants'change scores accounted for 16-19% of the variance in physical activity in men and 7-24% in women. Significant predictors were different for men and women. Present results can inform the design of physical activity interventions for these populations.

SUMMARY The association between physical fitness and blood pressure was studied in 2061 children selected from all fourth graders in 44 elementary schools in the New York City area. Their blood pressure and physical fitness were measured on two consecutive examinations 1 year apart. Systolic and diastolic blood pressure were highest in children with poor physical fitness. The change in physical fitness between the 2 examination years was related to the change in systolic and diastolic blood pressure (i.e., children with a decline in physical fitness showed the largest rise in blood pressure). These observations suggest that the level of systolic and diastolic blood pressure in children is associated with the level of physical fitness. They also indicate that change in blood pressure in childhood may be related to change in physical fitness. (Hypertension 9: 188-191, 1987) KEY WORDS epidemiology hypertension • blood pressure • physical fitness * childhood B LOOD pressure rises with age. Of the total lifetime increase in systolic blood pressure, about two thirds occurs in childhood, but the determinants of this rise early in life are still largely unknown. ' Physical exercise has been suggested to lower blood pressure in hypertensive adults, 2 " 6 and some observations suggest that the same may be true for adolescents. 78 However, only limited evidence is as yet available about an etiological relation between physical fitness and blood pressure in children. 9 We present the results of a study of the association between physical fitness and blood pressure in 2061 children living in the New York City area. Subjects and Methods PopulationThe source population for this study comprised all 4105 students in the fourth grade of 44 elementary schools in seven school districts in New York. Six of these school districts, with 1822 children, were located in Westchester County, and one school district, with 2283 children, was in the Bronx.

The population in the Bronx, 10 as well as in Westchester County," has been described in detail elsewhere.The children were eligible for participation in a study of the effectiveness of an intervention program (the Know Your Body [KYB] program) in modifying risk factors for chronic disease, notably blood pressure, serum lipid levels, body mass index, smoking habits, and physical fitness. In this study, 25 schools were randomly allocated to the intervention program and the remaining 19 schools s...

Lower Conditioning Leisure-Time Physical Activity in Young Adults Born Preterm at Very Low Birth Weight

et al. 2012

BackgroundAdults born preterm at very low birth weight (VLBW, <1500 g) have elevated levels of risk factors for cardiovascular diseases and type 2 diabetes. Preliminary observations suggest that this could partly be explained by lower rates of physical activity. The aim of this study was to assess physical activity in healthy young adults born preterm at very low birth weight compared with term-born controls.Methodology/Principal FindingsWe studied 94 unimpaired young adults, aged 21–29 years, born at VLBW and 101 age-, sex-, and birth hospital-matched term-born controls from one regional center in Southern Finland. The participants completed a validated 30-item 12-month physical activity questionnaire and the NEO-Personality Inventory based on the Big Five taxonomy, the most commonly used classification of personality traits. Yearly frequency, total time, total volume and energy expenditure of conditioning and non-conditioning leisure-time physical activity (LTPA) and commuting physical activity were compared between VLBW and term-born subjects. A subset of participants underwent dual-energy x-ray absorptiometry for body composition measurement. Data were analyzed by multiple linear regression. Compared with controls, VLBW participants had lower frequency [−38.5% (95% CI; −58.9, −7.7)], total time [−47.4% (95% CI; −71.2, −4.1)], total volume [−44.3% (95% CI; −65.8, −9.2)] and energy expenditure [−55.9% (95% CI; −78.6, −9.4)] of conditioning LTPA when adjusted for age, sex, body mass index, smoking, parental education and personality traits. Adjusting for lean body mass instead of body mass index attenuated the difference. There were no differences in non-conditioning LTPA or commuting physical activity.Conclusions/SignificanceCompared with term-born controls, unimpaired VLBW adults undertake less frequent LTPA with lower total time and volume of exercise resulting in lower energy expenditure. Differences in personality that exist between the VLBW and term-born groups do not seem to explain this association.
