Does the early introduction of solids promote obesity?

Childhood obesity is a major public health challenge across the developed world, and it is vital to understand the modifiable factors that contribute to it. The influence of early-life nutrition on predisposition to later obesity and metabolic disease is now well established. Much research has concentrated on the preventative effects of breastfeeding in relation to childhood obesity risk, but the optimal timing of introducing solid foods has received far less attention. This remains a much-debated and contentious issue, and differing guidelines from international bodies have caused confusion among parents. There is no conclusive evidence from current research that introducing solids before six months of age is associated with an increased risk of obesity in infancy or childhood. Current studies suggest that the most clearly established risk factor for childhood obesity is maternal body mass index. There is a need for continued research in this area.

The joy of parenting: infant sleep intervention to improve maternal emotional well-being and infant sleep.

INTRODUCTION: This study aimed to examine how improving infant sleep impacted the emotional well-being of mothers. METHODS: The participants were 80 mothers of infants aged 6-12 months; they attended a primary care medical clinic in Adelaide, Australia, for assistance with infant sleep problems. Behavioural intervention consisted of a 45-minute consultation, where verbal and written information describing sleep physiology and strategies to improve infant sleep was provided. Mothers were followed up 2-6 weeks later. Mothers rated their confidence (C), pleasure (P) and frustration (F) on a scale from 0 to 10, and completed the Depression Anxiety Stress Scale 21 at each consultation. The number of night-time awakenings and time taken to see an improvement in infant sleep were also reported. RESULTS: There was a significant increase in the C and P scores, and a significant decrease in the F scores (all p < 0.001). The mean total CPF score increased significantly from 14 to 25 (maximum score = 30). There was also a significant decrease in depression, anxiety and stress in the mothers (all p < 0.001). The mean number of maximum night awakenings also decreased significantly, from 4.9 to 0.5 (p < 0.001). The mean time taken to see improved infant sleep, as reported by the mothers, was 2.8 nights. CONCLUSION: A single consultation using a behavioural strategy to improve infant sleep was effective in improving infant sleep and in increasing maternal emotional well-being. In particular, the scores for 'pleasure in being a mother' increased dramatically.

Behavioral Management of Sleep Problems in Infants Under 6 Months--What Works?

OBJECTIVE: Crying and unsettled behavior in infancy is common. Prolonged disturbed infant sleep can have significant negative effects on the development of the child, and on the psychological well-being of the mother. Compared to studies examining the effects of behavioral sleep programs such as extinction-based techniques in infants over 6 months of age, fewer studies have looked at such strategies in infants under 6 months of age. The aim of this article is to summarize the literature examining the effects of behavioral techniques on infant sleep outcomes in the first 6 months of life and provide evidence based recommendations for the management of infant sleep disturbance. METHOD: An electronic search of the literature was performed to identify studies which examined the effects of a behavioral intervention aimed at improving sleep in infants under 6 months of age. RESULTS: Eleven studies were identified, of which 8 demonstrated improvements in infant sleep outcomes subsequent to the implementation of an educational behavioral program. CONCLUSION: Education directed to parents about the use of simple, prescriptive, behavioral techniques is effective in improving infant sleep. Long term follow-up studies have failed to find any negative effects on the child, either from a psychological or physical perspective.

Preventing early infant sleep and crying problems and postnatal depression: a randomized trial.

OBJECTIVE: To evaluate a prevention program for infant sleep and cry problems and postnatal depression. METHODS: Randomized controlled trial with 781 infants born at 32 weeks or later in 42 well-child centers, Melbourne, Australia. Follow-up occurred at infant age 4 and 6 months. The intervention including supplying information about normal infant sleep and cry patterns, settling techniques, medical causes of crying and parent self-care, delivered via booklet and DVD (at infant age 4 weeks), telephone consultation (8 weeks), and parent group (13 weeks) versus well-child care. Outcomes included caregiver-reported infant night sleep problem (primary outcome), infant daytime sleep, cry and feeding problems, crying and sleep duration, caregiver depression symptoms, attendance at night wakings, and formula changes. RESULTS: Infant outcomes were similar between groups. Relative to control caregivers, intervention caregivers at 6 months were less likely to score >9 on the Edinburgh Postnatal Depression Scale (7.9%, vs 12.9%, adjusted odds ratio [OR] 0.57, 95% confidence interval [CI] 0.34 to 0.94), spend >20 minutes attending infant wakings (41% vs 51%, adjusted OR 0.66, 95% CI 0.46 to 0.95), or change formula (13% vs 23%, P < .05). Infant frequent feeders (>11 feeds/24 hours) in the intervention group were less likely to have daytime sleep (OR 0.13, 95% CI 0.03 to 0.54) or cry problems (OR 0.27, 95% CI 0.08 to 0.86) at 4 months. CONCLUSIONS: An education program reduces postnatal depression symptoms, as well as sleep and cry problems in infants who are frequent feeders. The program may be best targeted to frequent feeders.

Reducing postnatal depression, anxiety and stress using an infant sleep intervention.

OBJECTIVE: To examine the psychological well-being of mothers following participation in a behavioural modification programme previously shown to improve infant sleep. DESIGN, SETTING AND PARTICIPANTS: A 45 min consultation with either a general practitioner (GP) or trained nurse providing verbal and written information describing sleep physiology in infants and strategies to improve infant sleep. Eighty mothers of infants 6-12 months of age with established infant sleep problems at a single general practice, Adelaide, South Australia. MAIN OUTCOME MEASURES: The Depression Anxiety Stress Scale 21 (DASS21) immediately prior to the first consultation and again at follow-up approximately 3 weeks later. The number of infant nocturnal awakenings requiring parental support was also reported by mothers on both occasions. RESULTS: All measures of maternal well-being and infant nocturnal awakenings improved significantly. The mean number of maximum nocturnal awakenings decreased from 5.0 to 0.5 (mean difference 4.4, 95% CI 3.4 to 5.5). All measures of DASS21 improved significantly. The mean total DASS21 decreased from 29.1 to 14.9 (mean decrease 14.2, 95% CI 10.2 to 18.2); mean depression decreased from 7.9 to 2.8 (mean difference 5.2, 95% CI 3.7 to 6.7); mean anxiety decreased from 4.6 to 2.6 (mean difference 2.0, 95% CI 0.7 to 3.2); mean stress decreased from 16.6 to 9.5 (mean difference 7.0, 95% CI 5.1 to 9.0). The proportion of mothers assessed as having any degree of depression decreased by 85% from 26/80 (32.5%) to 4/80 (5%). CONCLUSIONS: The number of nocturnal awakenings requiring parental support among infants aged 6-12 months significantly decreased following a single consultation on infant sleep physiology and teaching behavioural strategies to improve sleep. Significant improvements in maternal stress, anxiety and depression were also observed.

Feeding in the first year of life - emerging benefits of introducing complementary solids from 4 months.

BACKGROUND: Current World Health Organization guidelines recommend exclusive breastfeeding for the first 6 months of life. Breastfeeding conveys clear benefits to both mother and child. These benefits are likely to be amplified by prolonged feeding. OBJECTIVE: This article outlines the emerging evidence that suggests possible benefits from introducing complementary solids from 4 months of age in developed countries. DISCUSSION: The human gut may have a critical early window during which it has an opportunity to develop immunological tolerance. Introducing complementary solids from 4 months of age may decrease the risk of food allergy and coeliac disease - immunological illnesses that have become a public health priority. The new draft National Health and Medical Research Council guidelines recommend introducing solids at around 6 months (22-26 weeks). However, given recent evidence, it may be appropriate to recommend the introduction of solids from 4 months of age in the Australian context.

Effect of a consultation teaching behaviour modification on sleep performance in infants: a randomised controlled trial.

OBJECTIVE: To evaluate the effect of a behaviour modification program, taught to parents in a single visit to a trained nurse, in improving sleep performance in newborn infants, Australia. DESIGN: Randomised controlled trial. SETTING AND PARTICIPANTS: 268 families with normal newborn infants in the community, recruited between October 1996 and March 1997 from birth notices published in a South Australian daily newspaper. INTERVENTION: A 45-minute consultation with a nurse 2-3 weeks after the birth, including a tutorial discussion on normal sleep patterns in newborn infants, supported by retained written material and, for infants with weight gain < 30 g daily, referral to their usual postnatal care provider. MAIN OUTCOME MEASURES: Hours of daytime sleep (0600-1800), night sleep (1800-0600) and total sleep per 24 h; and number of daily records with total sleep >/= 15 h per 24 h, assessed by 7-day sleep diary at ages 6 and 12 weeks. RESULTS: 268 families returned at least one sleep diary (137/171 intervention, 131/175 control), recording 3273 days. Two intervention infants were referred for low weight gain. Total sleep time was 15 h or more per 24 h on 62% of recorded days in the intervention group, compared with 36% in the control group (P < 0.001). At 6 weeks of age, intervention infants slept a mean 1.3 h per day more than control infants (95% CI, 0.95-1.65), comprising a mean 0.5 h more night sleep (95% CI, 0.32-0.69) and 0.8 h more daytime sleep (95% CI, 0.56-1.07). At 12 weeks, intervention infants slept a mean 1.2 h per day more (95% CI, 0.94-2.14), comprising 0.64 h more night sleep (95% CI, 0.19-0.89) and 0.58 h more daytime sleep (95% CI, 0.39-1.03). There was no significant difference in crying time between the groups. CONCLUSIONS: A single consultation supported by written material in the first 3 weeks of a child's life improves sleep performance at 6 weeks of age. This improvement is maintained at 3 months.

Electronic medical records may be inadequate for improving population health status through general practice: cervical smears as a case study.

OBJECTIVE: [corrected] To determine whether routine electronic records are an accurate source of population health data in general practice through reviewing cervical smears rates in four South Australian practices. METHODS: The cervical screening rate in a purposive sample of four general practices (three rural and one urban) was obtained using an audit of medical records and a telephone follow-up. RESULTS: The cervical screening rate using only immediately available electronic medical records indicated an overall low rate for the participating practices (44.9%). However, telephone follow-up and adjustments to the denominator indicated the real rate to be 85.7%. The offer of appointments during the telephone follow-up further improved this rate for eligible women (93.8%). CONCLUSIONS AND IMPLICATIONS: Electronic medical records may be inadequate in preventive screening in general practice, without ensuring their accuracy. Updating records by telephone or personal follow-up produces a much more accurate denominator.
