North Star Takeaway: This study lays out a pilot trial testing Sleep GOALS, an online program designed to help postpartum people lose weight by addressing sleep, eating habits, and physical activity together. The researchers explain how they’ll run and evaluate the program to see if it’s doable, acceptable, and promising enough to test on a larger scale later.

North Star Takeaway: By analyzing the firsthand experiences of new mothers, this research identifies the specific barriers (such as exhaustion and time constraints) that make it difficult to maintain healthy habits during the postpartum period.

North Star Takeaway: This research examined national data and found that the timing of meals is a factor in weight management; individuals who successfully managed their weight often followed more consistent, timed eating schedules.

North Star Takeaway: This study found that pregnant people who increased their physical activity later in pregnancy reported less pain during their postpartum hospital stay compared to those who became less active. Overall, it suggests that staying active during pregnancy may help with pain and recovery after delivery.

North Star Takeaway: This study identified different patterns of when pregnant people eat during the day but found that these timing patterns weren’t strongly linked to how much weight they gained during pregnancy. Overall, it suggests that when food is eaten in midpregnancy may matter less for gestational weight gain than other factors.

North Star Takeaway: Using NHANES, they identified several “chrononutrition profiles” (like eating later/heavier vs. earlier) and linked them to multiple sleep health dimensions. Later/heavier eating patterns and certain timing gaps (like delaying the first meal after waking) were associated with worse sleep timing and/or duration.

North Star Takeaway: This study followed people with pre-pregnancy overweight/obesity to see how breastfeeding intentions lined up with what actually happened over time. It highlights that planning, starting, and continuing breastfeeding can diverge, pointing to when support may be most needed.

North Star Takeaway:They examined whether early-pregnancy “wear and tear” on the body (allostatic load) is linked with sleep-disordered breathing. Results suggest these stress-physiology markers and sleep breathing problems may be connected in early pregnancy, which matters because both relate to pregnancy health risks.

North Star Takeaway: This study found that older adults whose muscles were less efficient at producing energy tended to get tired more quickly during everyday walking. The takeaway is that improving muscle energy production could help reduce fatigue and support mobility as people age.

North Star Takeaway: The team tested whether different reviewers could apply the same reproducibility checklist to COVID-19 modeling papers and get consistent ratings. They found areas of strong agreement and weak agreement, which helps refine tools used to judge whether modeling studies are reproducible.

North Star Takeaway: Instead of looking at just one sleep measure, they combined several sleep dimensions into “multidimensional sleep health” and related it to gestational weight gain. Poorer overall sleep health was associated with differences in pregnancy weight gain patterns, reinforcing sleep as part of metabolic health in pregnancy.

North Star Takeaway: They tested whether sleep problems in mid-pregnancy tracked with blood sugar levels at the same time. The main finding was essentially “no clear association” between mid-pregnancy sleep disturbances and mid-pregnancy glycemia in their data.

North Star Takeaway: This study found that adults with more regular, higher-quality sleep and fewer problems falling asleep were less likely to have overweight or obesity at a given point in time. However, sleep patterns didn’t predict who gained or lost weight over time, suggesting sleep is linked to current weight status but not short-term weight change.

North Star Takeaway: This paper describes how they designed “ClockWork,” an intervention meant to use circadian science (daily timing) to support postpartum behaviors tied to cardiometabolic health. It’s a development paper—so the main contribution is how the program was built and why, setting up later testing

North Star Takeaway: This study found that when people ate during the day (like a shorter eating window) wasn’t linked to weight change over time. Instead, people who ate more meals per day tended to gain slightly more weight, suggesting meal frequency mattered more than meal timing for long-term weight.

North Star Takeaway: This study found that sleep can change the relationship between pregnancy physical activity and gestational weight gain. In other words, the “benefit” of activity for weight gain looked different depending on someone’s sleep characteristics.

North Star Takeaway: They created a new way to quantify how quickly older adults “fatigue” in everyday movement using accelerometers. The paper shows this measure is feasible and informative, helping researchers track real-world function decline.

North Star Takeaway: This study found that higher long-term stress on the body (called allostatic load) was linked to having chronic conditions like heart disease and diabetes, especially when people had both. It also showed that lifestyle factors like physical inactivity, poor sleep, smoking, and social inequalities play a big role, highlighting the need for targeted, culturally aware health interventions.

North Star Takeaway: This study found that most adults trying to lose weight don’t sleep well in all areas, especially when it comes to regular sleep schedules. Among people attempting weight loss, better overall sleep was linked to lower body weight and less weight gain.

North Star Takeaway: This study found that sleep-disordered breathing during pregnancy was not linked to babies being too small or too large once maternal body weight was taken into account. However, lower oxygen levels during sleep—especially when they worsened later in pregnancy—were associated with a higher chance of having a larger-than-average baby.

North Star Takeaway: They tested a postpartum lifestyle program for Latina women and looked specifically at sleep outcomes. The intervention produced measurable changes in sleep, showing sleep can shift along with broader lifestyle-focused programs..

North Star Takeaway: This trial piloted a self-management sleep program during pregnancy paired with a personal monitoring device. Results suggested the approach was promising for improving sleep-related outcomes, supporting larger trials.

North Star Takeaway: In people with type 1 diabetes, they found that higher skin intrinsic fluorescence (a marker related to long-term glycation/AGEs) predicted higher risk of death over time. However, that link became weaker after accounting for other health factors, meaning the results are suggestive but need to be confirmed in larger studies. It suggests this noninvasive measure may capture meaningful long-term risk.

North Star Takeaway: This paper focuses on whether a pregnancy sleep study using a monitoring device and randomized design is doable in real life. They found the approach was feasible enough to justify more research, including larger trials.

North Star Takeaway: They examined how physical activity and sleep relate in postpartum Hispanic women. The study shows these behaviors are linked in meaningful ways, reinforcing that postpartum health programs may need to address both together.

North Star Takeaway:This protocol describes a pilot trial testing a pregnancy sleep self-management program paired with a health-monitoring device. The goal is to see if the intervention is practical and acceptable and to collect early outcome signals.

North Star Takeaway: This study found that women who moved more—especially through aerobic exercise and weight training—tended to have hormone patterns linked to better health, like lower estrogen and higher protective hormones. Some of these effects were partly explained by body weight, suggesting activity and BMI work together to influence hormone levels.

North Star Takeaway: This study found that among Hispanic pregnant women, the type of physical activity mattered for sleep more than just how active someone was. Household and caregiving work were linked to poorer sleep, while activity done at work was linked to better sleep quality, suggesting not all movement has the same impact on sleep during pregnancy.

North Star Takeaway: They studied whether physical activity levels were linked to the chance of conceiving each cycle (“fecundability”) among women with prior pregnancy loss. They found that walking improved conception chances for overweight or obese women, while vigorous activity benefited women overall. These findings suggest that staying active is helpful for conception in this group, with no negative effects observed for moderate exercise or sitting.

North Star Takeaway: Using national data, they compared sitting/sedentary patterns in pregnant vs. non-pregnant women. They identified differences in how sedentary time is accumulated, which matters for designing realistic activity guidelines in pregnancy.

North Star Takeaway: This study tested whether a tailored exercise program during pregnancy could lower inflammation (measured by C-reactive protein) in women at higher risk for gestational diabetes. While women in the exercise group showed a small drop in inflammation, the difference wasn’t statistically significant overall—though those who kept up or increased exercise did see modest improvements.

North Star Takeaway: In older adults, more TV watching (a marker of sedentary behavior) predicted faster kidney function decline and higher CKD risk, while physical activity wasn’t as clearly tied to those outcomes. It suggests prolonged sedentary time may be especially important for kidney health.

North Star Takeaway: This was a feasibility randomized trial testing whether a pregnancy lifestyle program could realistically reduce gestational-diabetes risk factors in overweight/obese Hispanic women. They showed the trial approach was doable, informing how future, larger prevention studies should be built.

North Star Takeaway: They used accelerometers to track changes in physical activity and related those changes to arterial stiffness over time. The study suggests that increasing activity is linked with healthier blood vessel function (less stiff arteries).

North Star Takeaway: This randomized study tested an exercise intervention during pregnancy and evaluated whether it actually increased activity. The intervention successfully improved physical activity behaviors, showing structured programs can move the needle during pregnancy.

North Star Takeaway: This paper is basically a “how we did it” on enrolling veterans from primary care into an activity trial. It identifies what helped and what got in the way, offering practical lessons for recruitment in real healthcare settings.

North Star Takeaway: They linked activity and sedentary time to inflammation (CRP) during pregnancy. Light-intensity activity showed a protective association with CRP in pregnancy, suggesting even “not super intense” movement can matter.

North Star Takeaway: Using NHANES accelerometer and ABI data, they examined whether activity intensity relates differently to cardiovascular risk when someone already has a low ABI (a vascular risk marker). The results highlight that lower activity in this group is especially concerning, given their elevated baseline risk.

North Star Takeaway: In older adults, they found that stiffer arteries were associated with higher risk of developing kidney disease and faster kidney function decline. It supports a strong heart–kidney connection via vascular aging.

North Star Takeaway: Using BRFSS survey data, they looked at whether the PA–obesity relationship looks the same across racial/ethnic groups. They found the association differs by group, underscoring that self-reported activity doesn’t “translate” to obesity risk identically for everyone.

North Star Takeaway: They compared activity measured by device vs. self-report and related it to coronary artery calcification in older women. The study helps show how objective activity measures can better align with subclinical heart disease risk.

North Star Takeaway: In the SAVE trial, they examined how weight loss and insulin changes together related to arterial stiffness (pulse wave velocity). The key finding is that in young adults who are overweight, losing weight and lowering insulin levels together led to the biggest improvements in blood vessel stiffness. In short, weight loss helped most when it also improved how the body handles insulin.

North Star Takeaway: Using national data, they compared light vs. moderate-to-vigorous activity and CRP, considering diabetes status. The takeaway was that more moderate-to-vigorous activity was more strongly tied to lower inflammation than light activity, regardless of diabetes status.

North Star Takeaway: In NHANES, they found physical activity was associated with better kidney function (eGFR), though patterns differed somewhat by sex and diabetes status. It supports the broader idea that being more active is linked with healthier kidneys.

North Star Takeaway: This was one of the first major national looks at accelerometer-measured physical activity in U.S. adults (NHANES 2003–2004). They documented big differences by age, sex, and race/ethnicity, providing benchmark “real-world” movement levels.

North Star Takeaway: This is a concise clinical-style review summarizing how physical activity helps prevent type 2 diabetes. The main message is that regular activity improves insulin sensitivity and weight-related pathways, making diabetes less likely to develop.

North Star Takeaway: This invited commentary discusses the benefits/implications of “combined training” (typically aerobic + resistance) for diabetes-related outcomes. The overall point is that pairing training types can offer broader metabolic and cardiovascular benefits than focusing on only one mode.

North Star Takeaway: This study looked at whether when people eat—not just what they eat—relates to weight change over time, using a mobile app to track meal and sleep timing alongside medical record data. They found that skipping breakfast or eating most calories later in the day was linked to very small, not statistically significant weight increases, suggesting timing might matter, but more research is needed to be sure.

North Star Takeaway: Researchers tracked multiple dimensions of sleep (not just “hours,” but regularity, timing, efficiency, naps, etc.) in mid-pregnancy using actigraphy, then compared that to gestational weight gain. Individual sleep features weren’t strongly tied to weight gain, but certain overall “sleep profiles” were linked with a higher risk of low gestational weight gain compared with a healthy-sleep profile.

North Star Takeaway: Same conference abstract as above, presented in the Circulation supplement. Bottom line: the overall pattern of sleep health (sleep “profiles”) mattered more than any single sleep metric for identifying risk of low gestational weight gain.

North Star Takeaway: This study found that among older African Caribbean adults, replacing sedentary time with light physical activity (like gentle movement or walking) was linked to slightly better sleep quality. Surprisingly, for men, swapping sedentary or light activity for more intense exercise was associated with worse sleep efficiency, suggesting that lighter movement may be the most sleep-friendly option in this population.

North Star Takeaway: This study found that increasing physical activity during pregnancy was linked to less excessive weight gain only for people who were also getting enough, efficient sleep and feeling less daytime fatigue. In other words, physical activity seemed to work better for managing pregnancy weight when sleep was already in a healthier place.

North Star Takeaway: This abstract looks at how sleep and physical activity relate to depressive symptoms among women parenting young children.

North Star Takeaway: This study found that a culturally tailored diet and exercise program helped postpartum Latina women feel that their sleep quality improved over the first year after birth. However, it didn’t significantly change how long they slept, how quickly they fell asleep, or how rested they felt during the day.

North Star Takeaway: This abstract uses NHANES data to compare how health behaviors develop over time in youth with vs. without ADHD. It reports differences in behavior patterns (“trajectories”) by ADHD diagnosis.

North Star Takeaway: Using NHANES device-based activity data, this abstract compares objectively measured physical activity and sitting time by ADHD diagnosis.

North Star Takeaway: This abstract compares adolescents’ activity levels before vs. after childbirth. It reports that childbirth is associated with changes (typically reductions) in activity levels in this cohort.

North Star Takeaway: This study was a randomized trial that tested whether a personalized exercise program during pregnancy could lower levels of C-reactive protein (CRP)—a marker of inflammation linked to pregnancy complications—in women at high risk for gestational diabetes. The results suggested the exercise might slightly reduce CRP compared with a general health program, but the difference wasn’t statistically significant, meaning they couldn’t be sure it wasn’t due to chance.

North Star Takeaway: This abstract uses device-measured activity and sitting time and compares how each relates to body composition. It reports that physical activity and sedentary time show different relationships with body composition, and those patterns differ for pre- vs. post-menopausal women.

North Star Takeaway: This abstract links changes in physical activity with changes in insulin resistance (measured by HOMA-IR).

North Star Takeaway: This research looked at how different levels of everyday physical activity (measured with accelerometers) relate to cardiovascular risk in adults, especially focusing on people with a low ankle-brachial index (ABI), a marker of poor blood flow. It found that people with lower ABI tended to do less moderate-to-vigorous activity, and overall, being more active was linked to lower heart disease risk, suggesting that even small increases in movement might help heart health.

North Star Takeaway: This study looked at how changes in physical activity over time relate to changes in arterial stiffness — a measure of blood vessel health linked to heart disease — and found that increasing activity was associated with improvements in arterial stiffness, suggesting being more active may help cardiovascular health.

North Star Takeaway: This study found that people who move more—especially through light, everyday physical activity—tend to have better kidney function. The link was consistent for women and for men without diabetes, suggesting that even low-intensity movement may help support kidney health.
