Objective: To determine the mean duration of fussing and crying and prevalence of colic using modified Wessel criteria in infants in the first 3 months of life. Is there a universal 6 week crying peak and what is the prevalence of colic according to age and country?Study Design: A systematic literature search was performed using the databases Medline, PsycINFO and Embase. The major outcome measure was mean total fuss/cry duration during 24 hours at 1-2 weeks (11 samples), 3-4 weeks (6 samples); 5-6 weeks (28 samples), 8-9 weeks (9 samples) and 10-12 weeks (12 samples). Results:Of 5687 articles reviewed, 28 diary studies (33 samples) were suitable for inclusion in meta-analysis. The studies included 8690 infants. No statistical evidence for a universal crying peak at 6 weeks across studies was found. Rather, the mean fuss/cry duration across studies was stable at around 117-133 minutes (SDs: 66-70) in the first 6 weeks and dropped to a mean of around 68 minutes (SD: 46.2) by 10-12 weeks. Colic was much more frequent in the first 6 weeks (17-25%) than thereafter (11% by 8-9 weeks and 0.6% by 10-12 weeks) according to modified Wessel criteria and lowest in Denmark and Japan.Conclusions: Fuss/cry duration drops significantly after 8-9 weeks of age with colic as defined by modified Wessel criteria being rare in infants older than 9 weeks. Colic or excessive fuss/cry may be more accurately identified by defining fuss/cry above the 90 th percentile in the chart provided based on the review.

“…A recent review of studies examining the effect of birth order on parenting by Kaley et al [144] reports that evidence is scant and that to date, no studies have prospectively examined differences in parenting of first- and second-born siblings within the same family beginning at birth. However, the review identified several potentially modifiable postnatal factors affecting infant obesity risk: sleep duration, feeding style, and parental regulation of distress.…”

The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study

BackgroundBecause early life growth has long-lasting metabolic and behavioral consequences, intervention during this period of developmental plasticity may alter long-term obesity risk. While modifiable factors during infancy have been identified, until recently, preventive interventions had not been tested. The Intervention Nurses Starting Infants Growing on Healthy Trajectories (INSIGHT). Study is a longitudinal, randomized, controlled trial evaluating a responsive parenting intervention designed for the primary prevention of obesity. This “parenting” intervention is being compared with a home safety control among first-born infants and their parents. INSIGHT’s central hypothesis is that responsive parenting and specifically responsive feeding promotes self-regulation and shared parent–child responsibility for feeding, reducing subsequent risk for overeating and overweight.Methods/Design316 first-time mothers and their full-term newborns were enrolled from one maternity ward. Two weeks following delivery, dyads were randomly assigned to the “parenting” or “safety” groups. Subsequently, research nurses conduct study visits for both groups consisting of home visits at infant age 3–4, 16, 28, and 40 weeks, followed by annual clinic-based visits at 1, 2, and 3 years. Both groups receive intervention components framed around four behavior states: Sleeping, Fussy, Alert and Calm, and Drowsy. The main study outcome is BMI z-score at age 3 years; additional outcomes include those related to patterns of infant weight gain, infant sleep hygiene and duration, maternal responsiveness and soothing strategies for infant/toddler distress and fussiness, maternal feeding style and infant dietary content and physical activity. Maternal outcomes related to weight status, diet, mental health, and parenting sense of competence are being collected. Infant temperament will be explored as a moderator of parenting effects, and blood is collected to obtain genetic predictors of weight status. Finally, second-born siblings of INSIGHT participants will be enrolled in an observation-only study to explore parenting differences between siblings, their effect on weight outcomes, and carryover effects of INSIGHT interventions to subsequent siblings.DiscussionWith increasing evidence suggesting the importance of early life experiences on long-term health trajectories, the INSIGHT trial has the ability to inform future obesity prevention efforts in clinical settings.Trial registrationNCT01167270.

“…These factors include infant characteristics such as sex and temperament as well as environmental characteristics such as parental stress. Findings of sex differences in infant sleep patterns are mixed with some studies reporting sex differences (Anders, Halpern, & Hua, 1992; Bach, Telliez, Leke, & Libert, 2000; Kaley, Reid, & Flynn, 2012; Richardson, Walker, & Horne, 2010; So, Adamson, & Horne, 2007) but others reporting negligible or no differences (e.g., Tikotzky et al, 2010; Weinraub et al, 2012). Those studies reporting sex differences have found that males sleep less than females (Bach et al, 2000), particularly during the day (So et al, 2007), and have more frequent but shorter night wakings (Kaley et al, 2012; So et al, 2007), longer night wakefulness (Bach et al, 2000), and more sleep problems (Anders et al, 1992), such that overall females sleep more soundly than males (Richardson et al, 2010).…”

“…Studies examining temperament and various sleep outcomes during the first year have demonstrated temperament influences night, day, and total sleep duration (Kaley et al, 2012; Spruyt et al, 2008; Weissbluth, 1981), night wakings (Carey, 1974; Schaefer, 1990; Scher & Asher, 2004;Weinraub et al, 2012), and sleep problems (Kelmanson, 2004). Specifically, negative or difficult infant temperament has been associated with shorter sleep duration, particularly at night (Loutzenhiser & Sevigny, 2008; Weissbluth, 1981), and more night wakings (Weinraub et al, 2012) compared to positive or easy infant temperament, which has conversely been associated with greater night and total sleep duration (Kaley et al, 2012; Spruyt et al, 2008).…”

In contrast, some studies report weak or no associations between temperament and sleep (e.g., Anders et al, 1992; DeLeon & Karraker, 2007; Scher, Tirosh, & Lavie, 1998), which may be the result of age-dependent changes in this relation (Spruyt et al, 2008; Weinraub et al, 2012), or temperament’s differential relation with active compared to quiet sleep (Parslow et al, 2002).…”
