Parent-focused change to prevent obesity in preschoolers: results from the KAN-DO study.

OBJECTIVE: The study presents the immediate post-intervention results of Kids and Adults Now - Defeat Obesity!, a randomized controlled trial to enhance healthy lifestyle behaviors in mother-preschooler (2-5 years old) dyads in North Carolina (2007-2011). The outcomes include change from baseline in the child's diet, physical activity and weight, and in the mother's parenting behaviors, diet, physical activity, and weight. METHOD: The intervention targeted parenting through maternal emotion regulation, home environment, feeding practices, and modeling of healthy behaviors. 400 mother-child dyads were randomized. RESULTS: Mothers in the intervention arm, compared to the control arm, reduced instrumental feeding (-0.24 vs. 0.01, p<0.001) and TV snacks (-.069 vs. -0.24, p=0.001). There were also improvements in emotional feeding (p=0.03), mother's sugary beverage (p=0.03) and fruit/vegetable (p=0.04) intake, and dinners eaten in front of TV (p=0.01); these differences were not significant after adjustment for multiple comparisons. CONCLUSION: KAN-DO, designed to maximize the capacity of mothers as agents of change, improved several channels of maternal influence. There were no group differences in the primary outcomes, but differences were observed in the parenting and maternal outcomes and there were trends toward improvement in the preschoolers' diets. Long-term follow-up will address whether these short-term trends ultimately improve weight status.

Predictors of breastfeeding in overweight and obese women: data from Active Mothers Postpartum (AMP).

Excess maternal weight has been negatively associated with breastfeeding. We examined correlates of breastfeeding initiation and intensity in a racially diverse sample of overweight and obese women. This paper presents a secondary analysis of data from 450 women enrolled in a postpartum weight loss intervention (Active Mothers Postpartum [AMP]). Sociodemographic measures and body mass index (BMI), collected at 6 weeks postpartum, were examined for associations with breastfeeding initiation and lactation score (a measure combining duration and exclusivity of breastfeeding until 12 months postpartum). Data were collected September 2004-April 2007. In multivariable analyses, BMI was negatively associated with both initiation of breastfeeding (OR: .96; CI: .92-.99) and lactation score (ß -0.22; P = 0.01). Education and infant gestational age were additional correlates of initiation, while race, working full-time, smoking, parity, and gestational age were additional correlates of lactation score. Some racial differences in these correlates were noted, but were not statistically significant. Belief that breastfeeding could aid postpartum weight loss was initially high, but unrelated to breastfeeding initiation or intensity. Maintenance of this belief over time, however, was associated with lower lactation scores. BMI was negatively correlated with breastfeeding initiation and intensity. Among overweight and obese women, unrealistic expectations regarding the effect of breastfeeding on weight loss may negatively impact breastfeeding duration. In general, overweight and obese women may need additional encouragement to initiate breastfeeding and to continue breastfeeding during the infant's first year.

Gestational weight gain in consecutive pregnancies.

OBJECTIVE: The purpose of this study was to examine the association between gestational weight gain (GWG) in a woman's first and second pregnancies. STUDY DESIGN: We conducted a retrospective observational cohort study of 27,771 women with their first and second births in North Carolina's Pregnancy Nutrition Surveillance System database from 1996-2004. GWG was categorized as inadequate, appropriate, or excessive, according to 2009 Institute of Medicine guidelines. Covariate adjusted polytomous logistic regression was used to test the association between GWG category in the first and second pregnancy. RESULTS: Compared with women with appropriate GWG in their first pregnancy, women with excessive GWG in their first pregnancy had an odds ratio of 2.6 (95% confidence interval, 2.4-2.7) for excessive GWG in their second pregnancy. Women with inadequate GWG in their first pregnancy were similarly likely to repeat this category in their subsequent pregnancy. CONCLUSION: GWG category in a woman's first pregnancy is a significant predictor of GWG category in her subsequent pregnancy.

Effect of breastfeeding on weight retention from one pregnancy to the next: results from the North Carolina WIC program.

OBJECTIVES: Pregnancy-related weight retention can contribute to obesity, and breastfeeding may facilitate postpartum weight loss. We investigated the effect of breastfeeding on long-term postpartum weight retention. METHODS: Using data from the North Carolina Special Supplemental Nutrition Program for Women, Infants, and Children (WIC; 1996-2004), weight retention was assessed in women aged 18 years or older who had more than one pregnancy available for analysis (n=32,920). Using multivariable linear regression, the relationship between duration of breastfeeding after the first pregnancy and change in pre-pregnancy weight from the first pregnancy to the second pregnancy was estimated, controlling for demographic and weight-related covariates. RESULTS: Mean time between pregnancies was 2.8 years (standard deviation (SD) 1.5), and mean weight retention from the first to the second pregnancy was 4.9kg (SD 8.7). In covariate-adjusted analyses, breastfeeding for 20 weeks or more resulted in 0.39kg (standard error (SE) 0.18) less weight retention at the beginning of the second pregnancy relative to no breastfeeding (p=0.025). CONCLUSION: In this large, racially diverse sample of low-income women, long-term weight retention was lower among those who breastfed for at least 20 weeks.

Effect of breast-feeding on weight retention at 3 and 6 months postpartum: data from the North Carolina WIC Programme.

OBJECTIVE: Pregnancy-related weight retention can contribute to obesity, and breast-feeding may facilitate postpartum weight loss. We investigated the effect of breast-feeding on postpartum weight retention. DESIGN: A retrospective follow-up study of weight retention, compared in women who were fully breast-feeding, combining breast-feeding with formula-feeding (mixed feeding), or formula-feeding at 3 months (n 14 330) or 6 months (n 4922) postpartum, controlling for demographic and weight-related covariates using multiple linear regression. SETTING: The North Carolina Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). SUBJECTS: Participants in the North Carolina WIC Programme who delivered a baby between 1996 and 2004. RESULTS: In covariate-adjusted analyses, there was no association between breast-feeding and weight retention at 3 months postpartum. At 6 months postpartum, as compared to formula-feeders, mean weight retention was 0·84 kg lower in mixed feeders (95 % CI 0·39, 1·29; P = 0·0002) and 1·38 kg lower in full breast-feeders (95 % CI 0·89, 1·87; P ≤ 0·0001). CONCLUSIONS: Breast-feeding was inversely associated with weight retention at 6 months postpartum in this large, racially diverse sample of low-income women. Further, full breast-feeding had a larger protective effect than did breast-feeding combined with formula-feeding.

Occurrence and correlates of postpartum depression in overweight and obese women: results from the active mothers postpartum (AMP) study.

OBJECTIVE: Postpartum depression (PPD) is a significant concern for new mothers and their infants, as well as the health professionals who care for them. Obesity may be a risk factor for depression, and therefore, for PPD specifically. We examined the occurrence and risk factors for PPD in a sample of overweight and obese new mothers. METHODS: In this cross-sectional study, 491 women who were overweight or obese prior to pregnancy completed the Edinburgh Postnatal Depression Scale (EPDS) 6 weeks postpartum, along with a number of other health- and pregnancy-related measures. Occurrence of depression was investigated, as well as bivariate and multivariate relationships between depression and demographic and health-related characteristics. RESULTS: As determined by an EPDS score of 13 or higher, the prevalence of PPD was 9.2%. Three items on the scale stood out as drivers of the total score ("blame myself unnecessarily", "anxious or worried," "feel overwhelmed"). Bivariate correlates of depression included education, income, marital status, and self-reported chronic illness; income remained significant in the multivariate logistic regression model. BMI was not related to postpartum depression. DISCUSSION: In this group of overweight and obese women, there was no association between BMI group and postpartum depression.

Family physicians as team leaders: "time" to share the care.

A major contributor to shortfalls in delivery of recommended health care services is lack of physician time. On the basis of recommendations from national clinical care guidelines for preventive services and chronic disease management, and including the time needed for acute concerns, sufficiently addressing the needs of a standard patient panel of 2,500 would require 21.7 hours per day. The problem of insufficient time indicates that primary care requires broad, fundamental changes. The creation of primary care teams that include members such as physician assistants, nurse practitioners, dietitians, health educators, and lay coaches is important to meeting patients' primary care needs.

Estimated time spent on preventive services by primary care physicians.

BACKGROUND: Delivery of preventive health services in primary care is lacking. One of the main barriers is lack of time. We estimated the amount of time primary care physicians spend on important preventive health services. METHODS: We analyzed a large dataset of primary care (family and internal medicine) visits using the National Ambulatory Medical Care Survey (2001-4); analyses were conducted 2007-8. Multiple linear regression was used to estimate the amount of time spent delivering each preventive service, controlling for demographic covariates. RESULTS: Preventive visits were longer than chronic care visits (M = 22.4, SD = 11.8, M = 18.9, SD = 9.2, respectively). New patients required more time from physicians. Services on which physicians spent relatively more time were prostate specific antigen (PSA), cholesterol, Papanicolaou (Pap) smear, mammography, exercise counseling, and blood pressure. Physicians spent less time than recommended on two "A" rated ("good evidence") services, tobacco cessation and Pap smear (in preventive visits), and one "B" rated ("at least fair evidence") service, nutrition counseling. Physicians spent substantial time on two services that have an "I" rating ("inconclusive evidence of effectiveness"), PSA and exercise counseling. CONCLUSION: Even with limited time, physicians address many of the "A" rated services adequately. However, they may be spending less time than recommended for important services, especially smoking cessation, Pap smear, and nutrition counseling. Future research is needed to understand how physicians decide how to allocate their time to address preventive health.

Obesity and workers' compensation: results from the Duke Health and Safety Surveillance System.

BACKGROUND: Obese individuals have increased morbidity and use of health services. Less is known about the effect of obesity on workers' compensation. The objective of this study was to determine the relationship between body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) and number and types of workers' compensation claims, associated costs, and lost workdays. METHODS: Retrospective cohort study. Participants included 11 728 health care and university employees (34 858 full-time equivalents [FTEs]) with at least 1 health risk appraisal between January 1, 1997, and December 31, 2004. The main outcome measures were stratified rates of workers' compensation claims, associated costs, and lost workdays, calculated by BMI, sex, age, race/ethnicity, smoking status, employment duration, and occupational group. The body part affected, nature of the illness or injury, and cause of the illness or injury were also investigated. Multivariate Poisson regression models examined the effects of BMI, controlling for demographic and work-related variables. RESULTS: There was a clear linear relationship between BMI and rate of claims. Employees in obesity class III (BMI >/=40) had 11.65 claims per 100 FTEs, while recommended-weight employees had 5.80; the effect on lost workdays (183.63 vs 14.19 lost workdays per 100 FTEs), medical claims costs ($51 091 vs $7503 per 100 FTEs), and indemnity claims costs ($59 178 vs $5396 per 100 FTEs) was even stronger. The claims most strongly affected by BMI were related to the following: lower extremity, wrist or hand, and back (body part affected); pain or inflammation, sprain or strain, and contusion or bruise (nature of the illness or injury); and falls or slips, lifting, and exertion (cause of the illness or injury). The combination of obesity and high-risk occupation was particularly detrimental. CONCLUSIONS: Maintaining healthy weight not only is important to workers but should also be a high priority for their employers given the strong effect of BMI on workers' injuries. Complementing general interventions to make all workplaces safer, work-based programs targeting healthy eating and physical activity should be developed and evaluated.

Use of email in a family practice setting: opportunities and challenges in patient- and physician-initiated communication.

BACKGROUND: Electronic mail (email) has the potential to improve communication between physicians and patients. METHODS: We conducted two research studies in a family practice setting: 1) a brief, anonymous patient survey of a convenience sample to determine the number of clinic patients receptive to communicating with their physician via email, and 2) a randomized, controlled pilot study to assess the feasibility of providing health education via email to family practice patients. RESULTS: Sixty-eight percent of patients used email, and the majority of those (80%) were interested in using email to communicate with the clinic. The majority also reported that their email address changed less frequently than their home address (65%, n = 173) or telephone number (68%, n = 181). Forty-two percent were willing to pay an out-of-pocket fee to have email access to their physicians. When evaluating email initiated by the clinic, 26% of otherwise eligible patients could not participate because they lacked email access; those people were more likely to be black and to be insured through Medicaid. Twenty-four subjects agreed to participate, but one-third failed to return the required consent form by mail. All participants who received the intervention emails said they would like to receive health education emails in the future. CONCLUSION: Our survey results show that patients are interested in email communication with the family practice clinic. Our feasibility study also illustrates important challenges in physician-initiated electronic communication. The 'digital divide' - decreased access to electronic technologies in lower income groups - is an ethical concern in the use of email for patient-physician communication.

Ten dimensions of health and their relationships with overall self-reported health and survival in a predominately religiously active elderly population: the cache county memory study.

OBJECTIVES: To document the extent of healthy aging along 10 different dimensions in a population known for its longevity. DESIGN: A cohort study with baseline measures of overall self-reported health and health along 10 specific dimensions; analyses investigated the 10 dimensions as predictors of self-reported health and 10-year mortality. SETTING: Cache County, Utah, which is among the areas with the highest conditional life expectancy at age 65 in the United States. PARTICIPANTS: Inhabitants of Cache County aged 65 and older (January 1, 1995). MEASUREMENTS: Self-reported overall health and 10 specific dimensions of healthy aging: independent living, vision, hearing, activities of daily living, instrumental activities of daily living, absence of physical illness, cognition, healthy mood, social support and participation, and religious participation and spirituality. RESULTS: This elderly population was healthy overall. With few exceptions, 80% to 90% of persons aged 65 to 75 were healthy according to each measure used. Prevalence of excellent and good self-reported health decreased with age, to approximately 60% in those aged 85 and older. Even in the oldest old, the majority of respondents were independent in activities of daily living. Although vision, hearing, and mood were significant predictors of overall self-reported health in the final models, age, sex, and cognition were significant only in the final survival models. CONCLUSION: This population has a high prevalence of most factors representing healthy aging. The predictors of overall self-reported health are distinct from the predictors of survival in this age group and, being potentially modifiable, are amenable to clinical and public health efforts.

Alternative models for academic family practices.

BACKGROUND: The Future of Family Medicine Report calls for a fundamental redesign of the American family physician workplace. At the same time, academic family practices are under economic pressure. Most family medicine departments do not have self-supporting practices, but seek support from specialty colleagues or hospital practice plans. Alternative models for academic family practices that are economically viable and consistent with the principles of family medicine are needed. This article presents several "experiments" to address these challenges. METHODS: The basis of comparison is a traditional academic family medicine center. Apart of the faculty practice plan, our center consistently operated at a deficit despite high productivity. A number of different practice types and alternative models of service delivery were therefore developed and tested. They ranged from a multi-specialty office arrangement, to a community clinic operated as part of a federally-qualified health center, to a team of providers based in and providing care for residents of an elderly public housing project. Financial comparisons using consistent accounting across models are provided. RESULTS: Academic family practices can, at least in some settings, operate without subsidy while providing continuity of care to a broad segment of the community. The prerequisites are that the clinicians must see patients efficiently, and be able to bill appropriately for their payer mix. CONCLUSION: Experimenting within academic practice structure and organization is worthwhile, and can result in economically viable alternatives to traditional models.

Is there time for management of patients with chronic diseases in primary care?

PURPOSE: Despite the availability of national practice guidelines, many patients fail to receive recommended chronic disease care. Physician time constraints in primary care are likely one cause. METHODS: We applied guideline recommendations for 10 common chronic diseases to a panel of 2,500 primary care patients with an age-sex distribution and chronic disease prevalences similar to those of the general population, and estimated the minimum physician time required to deliver high-quality care for these conditions. The result was compared with time available for patient care for the average primary care physician. RESULTS: Eight hundred twenty-eight hours per year, or 3.5 hours a day, were required to provide care for the top 10 chronic diseases, provided the disease is stable and in good control. We recalculated this estimate based on increased time requirements for uncontrolled disease. Estimated time required increased by a factor of 3. Applying this factor to all 10 diseases, time demands increased to 2,484 hours, or 10.6 hours a day. CONCLUSIONS: Current practice guidelines for only 10 chronic illnesses require more time than primary care physicians have available for patient care overall. Streamlined guidelines and alternative methods of service delivery are needed to meet recommended standards for quality health care.

Making a home in the community for the academic medical center.

Academic medical centers (AMCs) have traditionally provided primary care for low-income and other underserved populations. However, they have had difficulty developing lasting partnerships with other organizations serving the same populations. This article describes an exception to the rule, in which an academic division was created at Duke University Medical Center to develop effective collaborations with health care and social service providers in Durham, North Carolina, including both public agencies and private organizations. Together, the division and its partners have created and operate programs that improve health outcomes and access to care for those at risk. These programs share a number of characteristics: they are designed to meet the needs of the patient, not the provider; they are based in the community, not in the AMC; they bring services to people's homes, schools, and neighborhoods; they are multidisciplinary, combining health, social, and even mental health services; and, once established, they are revenue-generating and can be made self-supporting when grant funding ends. These programs are also innovative. They are designed to model and test new ways of organizing and delivering care. Preliminary indications suggest that they also strengthen the AMC's relationships with the surrounding community.

The role of smoking and other modifiable lifestyle risk factors in maintaining and restoring lower body mobility in middle-aged and older Americans: results from the HRS and AHEAD. Health and Retirement Study. Asset and Health Dynamics Among the Oldest Old.

OBJECTIVES: To analyze the effect of smoking, smoking cessation, and other modifiable risk factors on mobility in middle-aged and older Americans. DESIGN: Panel study; secondary data analysis. SETTING: United States (national sample). PARTICIPANTS: The Health and Retirement Study (HRS) includes data on 12,652 Americans aged 50 to 61 in four waves (1992-1998). The Asset and Health Dynamics Among the Oldest Old (AHEAD) survey followed 8,124 community-dwelling people aged 70 years and older in three waves (1993-1998). MEASUREMENTS: The relationships between the primary outcome measure, lower body mobility (ability to walk several blocks and walk up one flight of stairs without difficulty), and smoking, exercise (HRS only), body mass index (BMI), and alcohol use were estimated in bivariate and multivariate analyses. RESULTS: Not smoking was strongly positively related to mobility, and the relative effects were similar in both panels. Among those with impaired mobility at baseline, not smoking was also strongly related to recovery. In the middle aged, there were consistent dose-response relationships between amount smoked and impaired mobility. Fifteen years after quitting, the risk of impaired mobility returned to that of never smokers. There was also a strong dose-response relationship between level of exercise and mobility. Inverted U-shaped relationships with mobility were observed for BMI and alcohol consumption. CONCLUSIONS: The relationships between not smoking and lower body mobility in middle-aged and older Americans are strong and consistent. Interventions aimed at reducing smoking have the potential to preserve mobility and thereby prolong health and independence in later life.

A problem-based approach to teaching outcomes research in family medicine residency.

OBJECTIVE: This study's objective was to introduce research concepts and skills in family medicine residency through a problem-based course. METHODS: Eight third-year residents per year in 3 academic years participated. Groups of two-three were presented with the task of developing, executing, and reporting on a small research project within the family medicine clinic. RESULTS: Residents' research skills and attitudes toward research improved. The projects resulted in successful presentations to colleagues and submissions to national conferences and peer-reviewed journals. CONCLUSIONS: This problem- based approach to research education for family medicine residents is productive and enjoyable.

Interest in healthy diet and physical activity interventions peripartum among female partners of active duty military.

Overweight and obesity among soldiers and their dependents have increased over the last decade, mirroring rates in the general population. In general, few programs that result in sustained weight loss have been evaluated, although effective interventions could have clear health and cost benefits for the military. For women, the postpartum period represents a "teachable moment" to promote healthy diet and exercise behaviors related to weight loss, but the attitudes and preferences for weight-loss interventions in this population are unknown. With a view to developing a weight-loss intervention tailored to this population, we surveyed 161 peripartum women at a military base to assess their interests and preferences. Eighty-six percent were dependents. Despite their youth, more than one-third reported entering pregnancy overweight or obese. Interest was high for interventions that promote physical activity and facilitate social interaction. Based on these results, a postpartum exercise intervention is being designed for female partners of active duty soldiers.

A 10-year follow-up of urinary and fecal incontinence among the oldest old in the community: the Canadian Study of Health and Aging.

Urinary incontinence is common in the elderly. The epidemiology of fecal and double (urinary and fecal) incontinence is less known. The Canadian Study of Health and Aging (CSHA) is a national study of elderly living in the community at baseline (n = 8,949) and interviewed in 1991-1992, 1996, and 2001. Using data from the CSHA, we report the prevalence of urinary, fecal, and double incontinence in each wave and the cumulative incidence between waves and investigate the predictors of urinary and fecal incontinence. Urinary incontinence increased rapidly in old age, being almost twice as high in women as in men. Fecal and double incontinence were less common, but also increased rapidly with age. In women, parity showed a positive relationship with (prevalent) urinary incontinence. In men, diabetes was a risk factor for urinary and fecal incontinence. We conclude that urinary, fecal, and double incontinence increase rapidly with age and that inquiry about incontinence should be part of routine medical and nursing assessment of all elderly.

Do high-risk preschoolers or overweight mothers meet AAP-recommended behavioral goals for reducing obesity?

BACKGROUND: The American Academy of Pediatrics (AAP) has issued specific behavioral recommendations to prevent obesity. It is unclear how often high-risk preschoolers and overweight mothers meet recommended behavior goals and whether meeting these goals is negatively associated with overweight/obesity. OBJECTIVE: To describe the proportion of preschoolers and mothers that meet AAP-recommended behavior goals and examine the associations of meeting goals with weight-status, and mothers meeting goals and children meeting corresponding goals. METHODS: Secondary analysis of baseline data (before an intervention) from mother-preschooler dyads in a weight-control study. Mothers were overweight or obese. Preschoolers were 2-5 years old. Dietary and feeding practices were assessed by the use of questionnaires. Activity was measured directly using accelerometry. Outcomes included preschooler overweight and maternal obesity. RESULTS: The respective proportions of children and mothers that met behavior goals were: 17% and 13% for ≥5 fruits/vegetables/day, 46% and 33% for zero sugar-sweetened beverages/day, 41% and 13% for fast-food <1×/week, and 46% and 13% for screentime ≤2 hours/day. Moderate-to-vigorous physical activity did not exceed 60 minutes/day in any participant. A total of 49% ate family meals together 7×/week. For each additional goal met, the adjusted odds for preschooler overweight was 0.9 (95% confidence interval 0.8-1.1) and for maternal obesity, 0.8 (95% confidence interval 0.6-0.9). Preschoolers had significantly greater odds of meeting each goal when mothers met the corresponding goal. CONCLUSIONS: Few high-risk preschoolers or overweight mothers meet AAP-recommended behavior goals. Meeting a greater number of behavior goals may be particularly important for maternal weight. Preschoolers have greater odds of meeting behavior goals when mothers meet behavior goals.

Diet quality and weight change among overweight and obese postpartum women enrolled in a behavioral intervention program.

BACKGROUND: Postpartum weight retention is a risk factor for long-term weight gain. Encouraging new mothers to consume a healthy diet may result in weight loss. OBJECTIVE: To assess predictors of diet quality during the early postpartum period; to determine whether diet quality, energy intake, and lactation status predicted weight change from 5 to 15 months postpartum; and to determine whether an intervention improved diet quality, reduced energy intake, and achieved greater weight loss compared with usual care. DESIGN: Randomized clinical trial (KAN-DO: Kids and Adults Now-Defeat Obesity), a family- and home-based, 10-month, behavioral intervention to prevent childhood obesity, with secondary aims to improve diet and physical activity habits of mothers to promote postpartum weight loss. PARTICIPANTS: Overweight/obese, postpartum women (n=400), recruited from 14 counties in the Piedmont region of North Carolina. INTERVENTION: Eight education kits, each mailed monthly; motivational counseling; and one group class. METHODS: Anthropometric measurements and 24-hour dietary recalls collected at baseline (approximately 5 months postpartum) and follow-up (approximately 10 months later). Diet quality was determined using the Healthy Eating Index-2005 (HEI-2005). STATISTICAL ANALYSES: Descriptive statistics, χ(2), analysis of variance, bi- and multivariate analyses were used. RESULTS: At baseline, mothers consumed a low-quality diet (HEI-2005 score=64.4 ± 11.4). Breastfeeding and income were positive, significant predictors of diet quality, whereas body mass index was a negative predictor. Diet quality did not predict weight change. However, total energy intake, not working outside of the home, and breastfeeding duration/intensity were negative predictors of weight loss. There were no significant differences in changes in diet quality, decreases in energy intake, or weight loss between the intervention (2.3 ± 5.4 kg) and control (1.5 ± 4.7 kg) arms. CONCLUSIONS: The family-based intervention did not promote postpartum weight loss. Reducing energy intake, rather than improving diet quality, should be the focus of weight-loss interventions for overweight/obese postpartum women.
