Bedtime in Preschool-Aged Children and Risk for Adolescent Obesity

Posted on by

An upcoming article (Journal of Pediatrics, (DOI: http://dx.doi.org/10.1016/j.jpeds.2016.06.005)shows an association between bedtime and the development of obesity:

Full-text link: Bedtime in Preschool-Aged Children and Risk for Adolescent Obesity

Abstract:

Objective

To determine whether preschool-aged children with earlier bedtimes have a lower risk for adolescent obesity and whether this risk reduction is modified by maternal sensitivity.

Study design

Data from 977 of 1364 participants in the Study of Early Child Care and Youth Development were analyzed. Healthy singleton-births at 10 US sites in 1991 were eligible for enrollment. In 1995-1996, mothers reported their preschool-aged (mean = 4.7 years) child’s typical weekday bedtime, and mother-child interaction was observed to assess maternal sensitivity. At a mean age of 15 years, height and weight were measured and adolescent obesity defined as a sex-specific body-mass-index-for-age ≥95th percentile of the US reference.

Results

One-quarter of preschool-aged children had early bedtimes (8:00 p.m. or earlier), one-half had bedtimes after 8:00 p.m. but by 9:00 p.m., and one-quarter had late bedtimes (after 9:00 p.m.). Children’s bedtimes were similar regardless of maternal sensitivity (P = .2). The prevalence of adolescent obesity was 10%, 16%, and 23%, respectively, across early to late bedtime groups. The multivariable-adjusted relative risk (95% CI) for adolescent obesity was 0.48 (0.29, 0.82) for preschoolers with early bedtimes compared with preschoolers with late bedtimes. This risk was not modified by maternal sensitivity (P = .99).

Conclusions

Preschool-aged children with early weekday bedtimes were one-half as likely as children with late bedtimes to be obese as adolescents. Bedtimes are a modifiable routine that may help to prevent obesity.

My take: Another potential reason to heed Samuel Jackson’s advice: Go the F- to Sleep (early)

Addicts and Anti-Diarrhea Drugs

Posted on by

According to NY Times:

Addicts Who Can’t Find Painkillers Turn to Anti-Diarrhea Drugs

Here’s an excerpt:

The active ingredient, loperamide, offers a cheap high if it is consumed in extraordinary amounts. But in addition to being uncomfortably constipating, it can be toxic, even deadly, to the heart.

A report published online in Annals of Emergency Medicine recently described two deaths in New York after loperamide abuse. And overdoses have been linked to deaths or life-threatening irregular heartbeats in at least a dozen other cases in five states in the last 18 months.

Most physicians just recently realized loperamide could be abused, and few look for it. There is little if any national data on the problem, but many toxicologists and emergency department doctors suspect that it is more widespread than scattered reports suggest.

Latest Obesity Data Discouraging

Posted on by

From LA Times (reporting on CDC study): In U.S., 38% of adults and 17% of kids are now obese

“How do government agencies, private foundations, industry groups and professional societies squander hundreds of millions of dollars? By trying to fight America’s obesity epidemic.

Two new studies show that the best efforts of all these players – as well as schools, churches and individual healthcare providers – have largely failed to keep most Americans from getting fatter.”

Politics and Limiting Physician Speech

Posted on by

A concise review/commentary (WE Parmet et al. NEJM 2016; 374: 2304-7) of Wollschlaeger v Governor of Florida explains how attempts to support the gun lobby are likely imposing unconstitutional limits on the free speech of physicians as well as undermining good health policy.

This law “prohibits physicians from intentionally entering into a patient’s record information about firearm ownership that ‘is not relevant to the patient’s medical care or safety, or the safety of others’; prohibits physicians from asking patients (or for minors, patients’ parents) about firearm ownership unless they believe ‘in good faith’ that ‘information is relevant to patient’s medical care or safety.'”

There are good reasons for physicians to inquire about guns in the homes as there is definitive evidence that a gun in the home increases the risk of death, especially by suicide.  The odds, on average from studies, is a 3-fold risk in homes with guns, but even higher for children and adolescents.

The law is counter productive as well. “Studies to date, as limited as they are, suggest that gun owners so counseled are more likely to change storage practices than to remove guns from their homes.”

While the politics with firearms is heavily influenced by well-funded lobbyists, there are other areas in which there are laws regulating physician speech, including abortion and fracking.

My take: I think it is outrageous that there are laws curtailing a physician’s free speech and efforts to dictate practice based on political philosophy. I hope they will not be upheld.

NPR: Getting Last-Ditch Experimental (Compassionate Use) Drugs

Posted on by

NPR: It’s Still Not Easy to Get Last-Ditch Experimental Drugs

An excerpt:

The Food and Drug Administration has reduced an obstacle from its compassionate use policy, streamlining paperwork that physicians must submit to obtain experimental drugs for patients with life-threatening illnesses.

Doctors will now file an application for FDA approval that contains just 11 questions, 15 fewer than the old form. They should be able to complete this new version in 45 minutes, the FDA said. The new form is simpler because it was designed for individual patients, replacing an all-purpose format that had been used by doctors acting on behalf of individuals or groups of patients…

Doctors still must first obtain a letter of authorization from that drug’s manufacturer. The FDA can’t compel drugmakers to grant permission. Manufacturers might reject requests because they’re worried about liability if the drug causes harm or they might consider the drug unsuited for a particular patient.

Balanced Summary of Probiotics & Microbiome Effects on the Brain

Posted on by

A good updated summary on probiotics from 538 GutScienceWeek:

Do probiotics work? Are they good for me?

This link reviews a good deal of science and has a nice table explaining costs.

Take home message: Probiotics which vary greatly by strain and often lack rigorous production standards may be beneficial for specific conditions like preventing antibiotic-induced diarrhea but probably are not beneficial on an ongoing basis.

The final post in the series looks at How the Gut Affects Your Mood.

While the author explains that there is likely a microbiome effect on the central nervous system as well as some intriguing animal studies, it is too early to know that manipulation of the microbiome will have beneficial effects on neurological/developmental concerns.

Tick Bites Can Lead to Allergy to Red Meat

Posted on by

From NBC News: Tick Bite Linked to Rise in Red Meat Allergies

Excerpt:

A tick-related meat allergy has been quietly spreading across the southern and eastern U.S. over the past two decades, but in recent years the number of cases have steadily risen. A tick bite in some people can kick off a sensitivity to red meat that can result in symptoms such as itching, hives, swollen lips and breathing problems. The reaction can sometimes be life threatening.

What is Missing in Doctors’ Toolkits

Posted on by

An excellent editorial provides insight into the complex interaction between social problems and health issues.  In this age of widespread information availability, the biggest problems are not solved by knowing everything and memorizing facts.  Solving problems with teamwork and identifying resources are increasingly important.

Here’s the link: NY Times: Giving New Doctors the Tolls They Need

Here’s an excerpt:

But consider the skills I would need to be more effective in just this one clinic session: understanding social issues that contribute to health; marshaling support resources like case management, social work and rehabilitation centers; exploring my patients’ values and goals and encouraging behavior change; leading interdisciplinary care teams; employing new technologies and methods of patient engagement like telemedicine; and appreciating how health systems fit together to influence an individual patient’s care — from home care and community centers to clinics and hospitals. None have traditionally been emphasized in medical education — and, unsurprisingly, doctors in training like myself are often ill-equipped to practice in today’s health care environment…

The new Dell Medical School at the University of Texas, Austin, which enrolls its first class in June, is hoping to revolutionize medical education. The school plans to focus on helping students understand how health systems, communities and social issues contribute to individual health through a variety of innovative methods.

Instead of traditional lecture halls, Dell’s students will learn in collaborative workspaces with a curriculum that emphasizes team-based management of patients. They’ll take weekly classes with pharmacy, nursing, social work and engineering students. Dell’s “Innovation, Leadership and Discovery” program affords students an entire year to pursue projects related to population health and delivery system redesign.

Dell also features a unique collaboration with the university’s College of Fine Arts — known as the Design Institute for Health — to bring design thinking to health care. Here students will learn to think about everything from better hospital gowns and more hospitable hospital rooms to how patients access services online and how to make waiting rooms obsolete.
