CCSU Science Essay

Introduction:

1. Summarize the background (from introduction) in 5 sentences or less.

2. Identify the specific questions.

Methods:

1. How was the purpose/problem addressed in this article? Identify the approach.

Results & Discussion

1.Write one or more paragraphs to summarize the results for each experiment, each figure, and each table. Don’t yet try to decide what the results mean, just write down what they are.

2.Do the results answer the SPECIFIC QUESTION(S)? What do you think they mean?

3.What do the authors think the results mean? Do you agree with them? Can you come up with any alternative way of interpreting them?

4. Do the authors identify any weaknesses in their own study? Do you see any that the authors missed? (Don’t assume they’re infallible!)

5. What do they propose to do as a next step? Do you agree with that?

6. How could the gerontologist practitioner use these findings?

Abstract
Introduction—To examine the association between sedentary behavior (SB), cardiometabolic
risk factors, and self-reported physical function by level of moderate-vigorous physical activity
(MVPA).
Author Manuscript
Methods—Cross-sectional analysis was completed on 1, 914 older adults aged ≥65 years from
the 2003–2006 U.S. National Health and Nutrition Examination Survey (NHANES). MVPA and
SB were derived from Actigraph accelerometers worn for one week. MVPA was categorized as
sufficient to meet the current U.S. guidelines (≥150 minutes/week) or not; SB was split into
quartiles. Various biomarkers were examined in laboratory analyses and physical exams, and the
number of functional limitations was self-reported. Statistical interaction between SB and MVPA
on the biomarker associations was the primary analysis, followed by an examination of their
independent associations with relevant covariate adjustment.
Author Manuscript
Results—Average SB was 9.4±2.3 hours/day (mean ± SD) and approximately 35% were
classified as sufficiently active. Overall, no significant meaningful statistical interactions were
found between SB and MVPA for any of the outcomes; however, strong independent positive
associations were found between SB and weight (p
