Background: The survival of horses diagnosed with critical colic (requiring referral or euthanasia) relies on rapid and effective decision-making by the owner and veterinary practitioner., Objectives: To explore UK horse owners' and veterinary practitioners' experiences of decision-making for critical cases of equine colic., Study Design: Qualitative study using a phenomenological approach., Methods: Individual, semi-structured telephone interviews were conducted with 14 horse owners and 13 veterinary practitioners (vets) who had experienced a critical decision (referral or euthanasia) for a horse with colic. A purposive, convenience sample of participants was recruited. Sessions explored participant's experience of colic, including recognition, help-seeking behaviour, and challenges. Thematic analysis was performed on collected data., Results: Four over-arching themes were identified; 'head', 'heart', 'practicalities' and 'impact'. Owners acknowledged responsibility for their horse's welfare but had different perspectives than vets on the importance of finance ('head'). Both vets and owners described how the horse-human relationship ('heart') often led to conflict during decision-making. The vet-client relationship was influential on decision-making for both owners and vets; involving other people in decision-making was described both positively and negatively by participants ('heart'). 'Practicalities', such as lack of preparedness, transport issues and adverse weather conditions, were identified by both owners and vets as barriers. Owners described a 'rollercoaster' of emotions after a critical decision, with profound impacts on their mental wellbeing, feelings of guilt, and long-term changes in behaviour ('impact'), and a lack of support to manage these feelings., Main Limitations: Small sample size., Conclusions: This study describes stakeholder decision-making during critical cases of equine colic. Factors that commonly influenced decisions included an owner's previous knowledge and beliefs, social pressures, logistics and the relationship between the owner and vet. The study highlighted long-term impacts on the owner, including their management and decisions for subsequent horses. These factors should be considered in shared decision-making., (© 2024 The Author(s). Equine Veterinary Journal published by John Wiley & Sons Ltd on behalf of EVJ Ltd.)

(1) Background: Infantile colic (IC) is a functional gastrointestinal disorder that affects around 20% of infants, and postpartum (PPD) depression is a common disorder that affects between 15 and 22% of mothers. In this study, our objective was to evaluate the relationship between the maternal psychological state in the first postpartum year and IC, with the aim of assessing the importance of feeding type in infants and maternal well-being. (2) Methods: A cross-sectional study was conducted in women in their first year postpartum. Demographic, medical, and obstetric data of the mothers and infants were collected, and the type of feeding was identified. The emotional status of the mother was evaluated using the Edinburgh Postnatal Depression Scale (EPDS), and the Infant Colic Severity Questionnaire (ICSQ) was used for IC diagnosis. (3) Results: A total of 528 women were analyzed, of which 170 (32%) were diagnosed with possible PPD. Two-thirds of the women without depression breastfed their babies on demand; therefore, we report that exclusive breastfeeding (EBF) appears to reduce the risk of possible PPD ( p < 0.001; OR = 2.353). IC was present in 39% of babies, and around 70% of babies without colic were breastfed on demand. Infants who were not exclusively breastfed showed almost double the risk of developing colic ( p = 0.016; OR = 1.577). There was a significant association between the EPDS and ICSQ scores ( p < 0.001). More than half of the women with PPD had babies with colic. However, our results show that 75% of babies without colic had mothers who reported optimal postpartum emotional well-being ( p < 0.001; OR = 2.105). (4) Conclusions: The results of this study suggest that postpartum maternal psychological well-being reduces the risk of IC. Therefore, we report that EBF on demand, together with a healthy emotional state in new mothers, may be a protective factor against colic in infants., Competing Interests: The authors declare no conflicts of interest.

Background: Given the possible effect of maternal anxiety on the severity of colic pain in infants, this study aimed to investigate the effects of behavioral therapy counseling on infantile colic (primary outcome), maternal anxiety, and mother-infant attachment (secondary outcomes) in anxious mothers with colicky infants., Method: This randomized controlled clinical trial was conducted on 46 anxious mothers of 2-6-weeks-old exclusively breastfed colicky infants who had a score of 112 and above according to the Postpartum Specific Anxiety Scale (PSAS), reffered to the pediatric clinics of Al-Zahra, Taleghani and Children Hospitals of Tabriz, Iran. The participants were randomly assigned to the intervention (n = 23) and control (n = 23) groups using randomized block design. Mothers in the intervention group attended 8 systematic desensitization counseling sessions (2-3 sessions per week). Those in the control group received routine care. The researcher completed the Postpartum Specific Anxiety Scale (PSAS), Mother-Infant Attachment Questionnaire (MIAQ), and Infant Colic Scale (ICS) by interviewing the participants before and two weeks after the intervention., Results: There was no significant difference between the intervention and control groups in the socio-demographic profile of participants. After the intervention, the mean postpartum anxiety score of women in the intervention group was significantly lower than that of those in the control group (Mean Difference (MD) = 22.5, 95% Confidence Interval (CI) = 2.3 to 42.7; p = 0.029). The mean infant colic score of the infants of mothers in the intervention group was insignificantly lower than that of those in the control group (MD = -2.9, 95% CI = -8.3 to 2.4; p = 0.271). In addition, no significant difference was observed between the two groups in terms of their mean mother-infant attachment scores (MD = -0.04, 95% CI = -3.1 to 0.3; p = 0.976)., Conclusion: Behavioral therapy counseling effectively reduced postpartum anxiety in women with colicky infants; however, this reduction did not lead to a significant decrease in the infants' colic pain. Therefore, health care providers are recommended to use this counseling method in combination with other effective counseling approaches to promote mental health of these mothers., Trial Registration: IRCT Registration Number: IRCT20111219008459N14, registered on 08/10/2020. https://irct.ir/user/trial/45949/view., (© 2022.

Purpose: The aim of this study was to determine maternal attachment and mental health status in mothers of babies with infantile colic., Design: Cross-sectional online survey., Setting: The study was conducted on messaging and social media platforms, and groups related to mothers and babies., Participants: 380 mothers, 107 of whom had babies with infantile colic and 273 of whom had healthy babies, participated in the study., Measurement Tools and Findings: A Personal Information Form, the Maternal Attachment Inventory, and the Depression, Anxiety and Stress Scale were used to collect data. No statistically significant relationship was found between infantile colic status and maternal attachment. The depression, anxiety and stress scores of the mothers who had babies with infantile colic were significantly higher compared to the mothers with healthy babies (p<0.05). Additionally, as the depression scores of the mothers increased, their maternal attachment levels decreased (p <0.05)., Key Conclusions: Maternal depression, anxiety and stress make it difficult for mothers to provide care for their babies. Therefore, health professionals should screen mothers who have babies with infantile colic in the postpartum period in terms of mental health. Besides, the mothers should be provided with support to assist them in coping with their Babies' colic., Implications for Practice: Health professionals should be aware that infantile colic negatively affects the mental health of mothers and increases the frequency of follow-ups of these mothers in the postpartum period. More research is needed to examine the effects of infantile colic on maternal attachment., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022.

Background: To characterize acoustic features of an infant's cry and use machine learning to provide an objective measurement of behavioral state in a cry-translator. To apply the cry-translation algorithm to colic hypothesizing that these cries sound painful., Methods: Assessment of 1000 cries in a mobile app (ChatterBaby TM ). Training a cry-translation algorithm by evaluating >6000 acoustic features to predict whether infant cry was due to a pain (vaccinations, ear-piercings), fussy, or hunger states. Using the algorithm to predict the behavioral state of infants with reported colic., Results: The cry-translation algorithm was 90.7% accurate for identifying pain cries, and achieved 71.5% accuracy in discriminating cries from fussiness, hunger, or pain. The ChatterBaby cry-translation algorithm overwhelmingly predicted that colic cries were most likely from pain, compared to fussy and hungry states. Colic cries had average pain ratings of 73%, significantly greater than the pain measurements found in fussiness and hunger (p < 0.001, 2-sample t test). Colic cries outranked pain cries by measures of acoustic intensity, including energy, length of voiced periods, and fundamental frequency/pitch, while fussy and hungry cries showed reduced intensity measures compared to pain and colic., Conclusions: Acoustic features of cries are consistent across a diverse infant population and can be utilized as objective markers of pain, hunger, and fussiness. The ChatterBaby algorithm detected significant acoustic similarities between colic and painful cries, suggesting that they may share a neuronal pathway.

Persistent, inconsolable crying in young infants is common, distressing but usually benign. This selective review examines perceptions and perceived origins of this phenomenon in babies where serious pathology has been excluded. Adult brains have evolved to become hypersensitive to infant cries. Babies respond to parental stress by crying more, thus setting up a vicious cycle. Most treatments appear to work largely through a placebo effect. The imperative for healthcare professionals is to reduce parental anxiety by offering reassurance and support., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Objective: To assess whether infants with colic that resolved before 6 months of age have poorer medium-term outcomes than infants without colic., Study Design: Comparative study of 2 prospective, community-based cohorts of children aged 2-3 years in Melbourne, Australia: children from the Baby Biotics study, with previously diagnosed Wessel criteria of colic without problem crying at 6 months (True Colic Cohort), vs children from the Baby Business trial, without problem crying at 1, 4, and 6 months (No Colic Cohort). Caregiver report of child internalizing and externalizing behaviors (primary outcome), temperament, regulatory (crying/sleeping/feeding) problems, and family functioning at child age 2-3 years was collected. We conducted regression analyses of mean differences/ORs adjusted for child sex, age, social disadvantage, parental education, and maternal mental health., Results: In total, 74% of the original Baby Biotics (n = 124) sample and 75% of the Baby Business (n = 503) sample completed questionnaires. In adjusted analyses, there were no significant differences between the True Colic Cohort (n = 99) and No Colic Cohort (n = 182) in internalizing behavior problems (adjusted mean difference 0.73; 95% CI -3.96 to 5.43, P = .76) or externalizing behavior problems (adjusted mean difference -1.53; 95% CI -6.02 to 2.97, P = .51). There were no statistically significant differences between groups in temperament, parental perception of regulatory problems, or family functioning., Conclusions: Infants with colic whose crying self-resolves do not experience adverse effects regarding child behavior, regulatory abilities, temperament, or family functioning in the medium term. Parents and clinicians can be reassured that infant crying as the result of colic, and related stress, is short-lived and will likely resolve., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Gastrointestinal (GI) disorders are common in autism spectrum disorder (ASD). Infant colic (IC), the functional GI disorder of infancy, has not been evaluated in this patient group. The aim of this study was therefore to determine the rate of IC in ASD and investigate a possible association between ASD and IC., Methods: The subjects consisted of 100 ASD patients (mean age, 6.6 ± 3.5 years) and 100 healthy controls (mean age, 5.3 ± 2.8 years). The parents were questioned using the diagnostic criteria for infant colic for clinical research purposes defined in Rome IV to diagnose IC, retrospectively. The sample size was estimated using a maximum type I error probability of 5% (alpha) and a type II error of 20%., Results: The rate of IC was 16% and 17% in the ASD group and control group, respectively (P ˃ 0.05). Excessive crying with late onset and long duration in infants was defined as persistent crying. The rate of persistent crying was significantly higher in the ASD group than in the control group (32% vs 9%, P < 0.001). The relative risk of persistent crying was 4.40 in ASD. The likelihood of being misdiagnosed with IC in this group was 78%., Conclusion: The rate of IC is not increased in patients with ASD, but infants with excessive crying should be very thoroughly evaluated before being diagnosed with IC. In particular, persistent crying in infants (i.e. excessive crying with late onset and long duration) may be an early symptom of ASD., (© 2018 Japan Pediatric Society.)

Background: While biological and behavioral stress response systems are intact in early gestation, preterm infants' behaviors are often more subtle and difficult to interpret compared with full-term infants. They are also more vulnerable for regulatory issues (ie, colic) that are known to impact caregiver-infant interactions. Biobehavioral measures such as behavioral responsivity and heart rate variability (HRV), particularly cardiac vagal tone, may help elucidate preterm infants' stress/regulatory systems., Purpose: To test the hypotheses that preterm infants' consoling behaviors and high-frequency (HF) HRV in the first week of life are significantly associated and they are inverse correlates of future colic risk., Methods/search Strategy: Thirty preterm (mean ± SE = 32.7 ± 0.3 weeks postmenstrual age [PMA]) infants underwent direct NIDCAP (Newborn Individualized Development and Assessment Program) observation during routine care and had HRV measurements during their first week postbirth. Sixty-three percent of mothers completed the Infant Colic Scale at 6 to 8 weeks adjusted postnatal age. Nonparametric tests were used to determine associations among behaviors, HRV, and maternal perceptions of infant colic., Findings/results: Self-consoling behaviors were positively associated with HF-HRV (vagal tone). In addition, stress behaviors were positively associated with low-frequency/high-frequency HRV (sympathetic dominance). Infants who displayed more stress behaviors also demonstrated more self-consoling behaviors. No significant associations were found with colic., Implications for Practice: HF-HRV provides information on the infant's capacity to modulate stress and is a useful, noninvasive measure when behaviors are more difficult to discern., Implications for Research: Further study in a larger sample is needed to determine whether behavioral stress measures and HF-HRV may be useful to determine colic risk.

Aims and Objective: This study aimed to compare the effects of swinging and playing of white noise on the crying and sleeping durations of colicky babies., Background: Infantile colic (IC) is one of the most common reasons for doctor visits among babies younger than 3 months. One of five babies older than 3 months also experiences IC. IC, unlike gastrointestinal problems, is regarded as an individual differentiation and maturation of the central nervous system. Providing a warm bath, breastfeeding, swinging and playing of white noise are nonpharmacological methods. The efficiency of these methods has been proven by various studies independently of one another., Design: The study is a prospective, multicentre, paired randomised controlled trial., Methods: The study was conducted between April-December 2016. The study sample consisted of 40 1-month-old babies with gas pains who passed a hearing screening and their mothers. The total daily crying and sleeping durations of the babies were determined without any intervention on the first week. On the second week, 20 randomly selected babies (first group) were swung each time they cried, and on the third week, they were made to listen to white noise. The other 20 babies (second group) were made to listen to white noise on the second week and were swung on the third week. Swinging and playing of white noise were performed until the babies stopped crying. After every intervention, the total crying and sleeping durations of the babies were evaluated using a "Colicky Baby's Diary.", Results: Playing of white noise significantly decreased the daily crying durations (p < .05) and increased the sleeping durations of the colicky babies (p < .05) compared to swinging in both groups., Conclusion: Playing of white noise was found to be a more effective nonpharmacological method on crying and sleeping durations of colicky babies than swinging., Relevance to Clinical Practice: Playing of white noise may be helpful for parents and healthcare personnel in reducing the gas pains of babies., (© 2017 John Wiley & Sons Ltd.)

Objectives: To evaluate crying time, retinoid-related orphan receptor-γ (RORγ) and forkhead box P3 (FOXP3) messenger RNA levels (transcription factors that can modulate T cell responses to gut microbes), and to investigate gut microbiota and fecal calprotectin in infants treated with Lactobacillus reuteri for infantile colic., Study Design: A double-blind, placebo-controlled randomized trial was conducted in primary care in Torino from August 1, 2015 to September 30, 2016. Patients suffering from infantile colic were randomly assigned to receive daily oral L reuteri (1 × 10 8  colony forming unit) or placebo for 1 month. Daily crying times were recorded in a structured diary. FOXP3 and RORγ messenger RNA in the peripheral blood was assessed with real-time TaqMan reverse transcription polymerase chain reaction. Gut microbiota and fecal calprotectin were evaluated., Results: After infants with colic were supplemented with L reuteri DSM 17938 for 30 days, crying times were significantly shorter among infants with colic in the probiotic group compared with infants in the placebo group (74.67 ± 25.04 [IQR = 79] minutes /day vs 147.85 [IQR = 135] minutes /day [P = .001]). The FOXP3 concentration increased significantly (P = .009), resulting in decreased RORγ/FOXP3 ratios: 0.61 (IQR = 0.60) at day 0 and 0.48 (IQR = 0.28) at day 30 (P = .028). Furthermore, the probiotic increased the percentage of Lactobacillus (P = .049) and decreased fecal calprotectin (P = .0001)., Conclusions: Infants with colic treated with L reuteri for 30 days had a significantly decreased crying time and an increased FOXP3 concentration, resulting in a decreased RORγ/FOXP3 ratio. The treatment reduced fecal calprotectin., Trial Registration: ClinicalTrials.gov: NCT00893711., (Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.)

Background: Maternal psychological factors like depression, anxiety and stress have been associated with infant fussiness or colic. However, little research exists on whether positive factors such as social support and the happiness of the mother-partner relationship are associated with lower rates of infant fussiness or colic., Objectives: We investigated the association between infant colic and three types of maternal support: general maternal social support (during pregnancy and post partum), the happiness of the mother-partner relationship (during pregnancy and post partum) and partner involvement in caring for the newborn., Methods: Participants were 3006 women in the First Baby Study, a prospective study of the effect of mode of first delivery on subsequent childbearing. Women were interviewed by telephone during pregnancy and 1 month after first childbirth and asked about social support and if their baby had a variety of problems since birth, including 'Colic - crying or fussiness three or more hours a day'. Multivariable logistic regression models were used to model the association between maternal support and infant colic, controlling for confounders, including maternal race or ethnicity, insurance, marital status, smoking, mode of delivery, maternal post-partum depression, breastfeeding, other neonatal illnesses and newborn gestational age., Results: Infant colic was reported by 11.6% of new mothers. High general maternal social support (in comparison with low), measured during pregnancy, was associated with lower reported infant colic (adjusted odds ratio (AOR), 0.55, 95% confidence interval (CI), 0.40-0.75) and measured post partum (AOR, 0.51, 95% CI, 0.39-0.67); high relationship happiness (in comparison with low), measured during pregnancy (AOR, 0.71, 95% CI, 0.54-0.93), and measured post partum (AOR, 0.22, 95% CI, 0.12-0.40); and high partner involvement with newborn care (in comparison with low) (AOR, 0.60, 95% CI, 0.44-0.81)., Conclusion: Higher levels of maternal social support during pregnancy and post partum are associated with lower rates of maternal reported infant colic., (© 2017 John Wiley & Sons Ltd.)

Background: Infant colic occurs between 10% and 40% of healthy born children in their first year of life. Its assessment is complex, and there are only a few instruments of appraisement and diagnosis., Methods: Scientific articles located through a systematic review using the Pubmed, Scopus, Cochrane, PEDro, Dialnet, IME and Dialnet databases. Two researchers obtained data independently from relevant studies previously identified. Risk of bias was assessed according to the methods recommended by the Cochrane Collaboration, with reporting following the preferred reported items for systematic reviews and meta-analyses guidelines and evaluating their methodological quality based on the EMPRO scale., Results: Four tools were obtained for valuation of infant colic. Parental diary of infant cry and fuss behaviour, Crying Pattern Questionnaire, Infant Colic Scale and, lastly, a validity of the Turkish version of the Infant Colic Scale., Conclusions: Analysis of the existing tools involves the need to design and validate new assessment scales for this clinical frame., (© 2017 John Wiley & Sons Ltd.)

Background: Evidence for treating infantile colic with acupuncture is contradictory., Aim: To evaluate and compare the effect of two types of acupuncture versus no acupuncture in infants with colic in public child health centres (CHCs)., Methods: A multicentre, randomised controlled, single-blind, three-armed trial (ACU-COL) comparing two styles of acupuncture with no acupuncture, as an adjunct to standard care, was conducted. Among 426 infants whose parents sought help for colic and registered their child's fussing/crying in a diary, 157 fulfilled the criteria for colic and 147 started the intervention. All infants received usual care plus four extra visits to CHCs with advice/support (twice a week for 2 weeks), comprising gold standard care. The infants were randomly allocated to three groups: (A) standardised minimal acupuncture at LI4; (B) semi-standardised individual acupuncture inspired by Traditional Chinese Medicine; and (C) no acupuncture. The CHC nurses and parents were blinded. Acupuncture was given by nurses with extensive experience of acupuncture., Results: The effect of the two types of acupuncture was similar and both were superior to gold standard care alone. Relative to baseline, there was a greater relative reduction in time spent crying and colicky crying by the second intervention week (p=0.050) and follow-up period (p=0.031), respectively, in infants receiving either type of acupuncture. More infants receiving acupuncture cried <3 hours/day, and thereby no longer fulfilled criteria for colic, in the first (p=0.040) and second (p=0.006) intervention weeks. No serious adverse events were reported., Conclusions: Acupuncture appears to reduce crying in infants with colic safely., Trial Registration Number: NCT01761331; Results., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

Background  Abdominal pain, cramping, and discomfort (APCD) are experienced by up to 30 % of adults in Europe. Objective  To assess the impact of APCD on quality of life (QoL) and to investigate the effectiveness, tolerability, and impact on QoL of hyoscine butylbromide (HBB, Buscopan ® ) compared with STW 5 (Iberogast ® ) or analgesics in women with APCD. Methods  An internet-based observational pilot study was conducted in Germany in women who had predominantly used HBB, STW 5, or analgesics (n = 240 per treatment) to treat APCD. This online survey included questions on QoL, effectiveness, and tolerability. Results  A total of 720 completed questionnaires was evaluated. APCD had a major impact on QoL, with 96 % of women reporting that daily activities were disrupted at least sometimes, and 44 % at least often. Other aspects of QoL, such as quality of work, eating habits, and social activities, were also affected in most women. After taking their medication of choice, 91 % of women in the HBB group reported they could "very often" or "often" continue with their daily activities, compared with 84 % and 85 % in the STW 5 and analgesic groups, respectively (p < 0.05 for both comparisons). HBB was perceived to be the "best solution" to overcome APCD symptoms "very often" or "often" by more women (86 %) than STW 5 (75 %) and analgesics (74 %) (p < 0.05 for both comparisons). Conclusion  Women with APCD have impaired QoL. All treatments were considered effective by the majority of participants. Compared with STW 5 or analgesics, HBB was reported to facilitate return to daily activities more frequently., (© Georg Thieme Verlag KG Stuttgart · New York.)

The term 'infant colic' has been used to refer both to 'prolonged' infant crying (a measure of crying) and to parents'concern thatexcessive'crying is a sign that something is wrong with their baby. There is growing evidence that the terms need to be distinguished, so that the traditional focus on the crying is balanced by an equal focus on the impact of the crying on parents. The Surviving Crying study is a first step towards developing and evaluating routine NHS services to support parents who are worried about their baby's excessive crying. This report summarises the study's overall aims and methods and describes the first stage, designed to develop this parental support package. The package comprises a website, printed materials for parents who do not use the internet and a CBT-based programme manual for delivering direct one-to-one or small-group support sessions to parents. Stage two of the study, designed to provide an initial evaluation of the package and its suitability for use in the NHS, is underway. An email address exists for practitioners and researchers who wish to be kept informed.

Background: Probiotic Lactobacillus reuteri and reduced allergen load may lessen the daily crying of colic infants, but the role of Lactobacillus rhamnosus GG (LGG) has remained obscure., Methods: Infants with colic (n = 30) were enrolled during the first 6 wk of life. All families received behavioral support and allergen avoidance diet: breastfeeding mothers followed cow's milk elimination diet and formula-fed infants received extensively hydrolyzed casein formula. The randomized, double-blind intervention employed of LGG 4.5 × 10(9) cfu/d or placebo for a 4-wk study period. Daily crying was recorded by diaries and parental interviews. Fecal calprotectin and gut microbiota composition by quantitative PCR were evaluated before and after the intervention., Results: Daily crying time was comparable between the probiotic (173 min) and the placebo group (174 min; P = 0.99) at the end of the intervention according to the parental diary. However, parents reported a decrease of 68% (95% confidence interval (CI): 58-78) in daily crying in the probiotic and 49% (95% CI: 32-66) in the placebo group (P = 0.05)., Conclusion: LGG in infants treated in tandem with behavioral support and a cow's milk elimination diet did not provide additional treatment effect for diary-verified colic crying although parental report of crying suggested the probiotic intervention effective.

Infant colic, excessive crying of unknown cause, is a major burden to families and effects about 10-30 % of infants. Despite decades of research, the exact cause and treatment of infant colic has remained elusive. The use of Lactobacillus reuteri (DSM 17938) in infant colic is somewhat controversial and hence, we designed this study to evaluate its efficacy in infantile colic. We recruited predominantly or exclusively breastfed infants, aged less than 4 months in a placebo controlled observational randomized study. Participants' were assigned to receive L. reuteri at a dose 10(8) colony forming units (n = 21) and placebo (n = 21). Placebo was an identical formulation without live micro-organisms. Treatment was given to subjects for 21 days and they were followed for 4 weeks. Treatment success (primary outcome), daily reduction in crying time, parent satisfaction and reduction in maternal depression (secondary outcomes) were assessed at the end of study period. Treatment success was observed in all infants (100 %) of the probiotic group while it was seen in 15.7 % of the placebo group. Mean daily crying time was more significantly reduced to 32.1 ± 8.3 min/day (P < 0.01) from 200.9 ± 6.3 min/day in the probiotic group as compared to the placebo group (120.6 ± 20.0 min/day). Moreover, throughout the study period, parent's satisfaction and improvement in maternal depression (Edinburgh postnatal depression scale) was also significantly higher in the probiotic group. In our study population, reduction in crying time was significant (P < 0.01) even during first week of initiation of therapy. We conclude that L. reuteri (DSM 17938) reduces daily crying time and maternal depression during infantile colic. We suggest L. reuteri may be a safe and efficacious option for reducing infant colic.

The devastating and for the most part irremediable consequences for an infant, his or her family, and society in cases of abusive head trauma have spurred research into ways of preventing it. In the last four or five decades, increasing interest in infant crying and its clinical manifestation of colic has led to a reconceptualization of crying in early infancy, such that most of the characteristics of colic can be understood as manifestations of the crying typical of normal infants. This includes an early increase and then decrease in the amount of crying, the unexpected and unpredictable appearance of prolonged crying bouts, and the presence of inconsolable crying that occurs in the early months of life. When these concepts are merged with anecdotal clinical experiences, perpetrator confessions and epidemiological evidence of abusive head trauma, it is clear that these crying characteristics--and caregiver responses--are the predominant, and potentially modifiable, risk factors for abusive head trauma. This unfortunate but understandable relationship between early crying, shaking and abuse has opened windows of opportunity for primary, universal prevention efforts that are appropriate for--and support--all parents and may be able to prevent at least some of these tragic cases.

Aim: The diagnosis of infantile colic is based on excessive crying. However, several causal factors can account for this disconcerting, nonspecific symptom. The main aim of this study was to investigate a possible association between excessive crying during the first 6 months of life and subsequent ear problems., Methods: Data from a cohort study of 26 983 Danish children were used. Mothers participated in four telephone interviews and one questionnaire and provided information on crying in the first 6 months of life and ear symptoms at the ages of 6 months, 18 months and 7 years., Results: There was a statistically significant association between excessive crying in infancy and subsequent ear symptoms. A gradual increase in subsequent ear problems was seen with increasing crying time at all the data collection times., Conclusions: The results of this study suggest a possible link between excessive crying and ear infections. Whether such a link is causal or due to common underlying factors is still unknown. We recommend thorough ear examinations in children with symptoms compatible with infantile colic., (©2014 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.)

Background: Infants' continuous crying is a challenge both for the child and the principal caregiver. However, the links between infants' sleep, crying and cortisol secretion and mothers' well-being and sleep have been scarcely investigated. The aim of the present study was therefore to examine the link between cortisol secretion, crying and sleep of infants characterized by infantile colic (IC) and mothers' psychological well-being and own sleep., Methods: Mothers of 24 infants characterized by IC (mean age = 8 weeks, SD = 1.5 weeks) completed a series of questionnaires regarding the infant's crying and sleeping patterns. Infants' sleep was objectively assessed with actigraphs. Cortisol secretion was measured by means of saliva samples in the mornings after waking. After 4 weeks, infants were assessed once again. Mothers completed questionnaires assessing their psychological well-being (depressive symptoms, family strain) and sleep., Results: Mothers' psychological well-being and sleep was greatly predicted by infants' morning saliva cortisol levels, sleep disruptions and crying intensity, whereas infants' crying duration and volume had low predictive value., Conclusions: Mothers with infants characterized by IC are at increased risk for reporting impaired sleep, developing depressive symptoms and reporting higher family strain. Most importantly, this risk seems to be greater if their infants' sleep is fragmented.

We aimed to measure the psychosocial status and quality of life in mothers of babies with infantile colic (IC). Mothers and their newborns were stratified into Group 1 (colicky infant-mother dyad [n: 39]) and Group 2 (non-colicky infant-mother dyad [n: 39]). Maternal symptoms of depression and anxiety were assessed using the Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI), respectively. The Short Form-36 (SF36) was used to measure quality of life. Mean BDI score in Group 1 (14.7 ± 12.9) was significantly higher than in Group 2 (7.7 ± 5.5) (p=0.020). Mothers in Group 1 had lower Short Form- 36 physical functioning (26.6 ± 4.3 vs. 28.7 ± 2.6; p=0.010) and social functioning (7.4 ± 2.5 vs. 8.9 ± 3.2, p=0.024) domain scores. Infantile colic (IC) was associated with higher maternal depression symptom scores and lower quality of life scores. As such, we think that mothers who have babies with IC should be closely monitored.

Introduction: The purpose of this study was to describe mothers' experiences of parenting an irritable infant. Although "colic" is regarded as a "self-limiting" condition that usually disappears by 3 to 4 months of age, the entire family is affected by the infant's crying; no definitive cause or cure has been identified., Sample and Setting: Twelve middle-class married mothers (mean age=27.6 years) of irritable infants were interviewed. The women responded to open-ended questions, beginning with a description of the "typical day" with the infant. All interviews were tape recorded, transcribed verbatim, and entered into the AtlasTi qualitative analysis program. Grounded theory methods were used to analyze the data. Transcripts were read repeatedly to verify coding and emerging concepts., Results: The basic social psychological problem was the loss of the perceived baby and competence as a mother. The psychosocial process was the search for the baby and sense of self as mother. Processes involved cycles of hope and despair and trial and error as mothers became more isolated., Discussion: Implications for practitioners include support and listening to mothers during this difficult period., (Copyright © 2011 National Association of Pediatric Nurse Practitioners.

The persistent and unexplained crying of newborns, attributed to colic, is a frequent problem in paediatrics. Usually considered harmless, it can however have consequences on the baby's behaviour and emotional regulation. Moreover, mothers often misinterpret the crying. Faced with the maternal anxiety which is often associated, treatment must be multifocal.

Purpose: To elucidate the experience of fathers living with a colicky infant., Study Design and Methods: Interpretive phenomenology using in-depth interviews with 10 fathers of colicky infants. Reiterative interview reading, repeated meaning unit sorting, going back to the literature, and discussions gave way to emerging themes., Findings: The overall experience is one of "falling into and arising from the crying abyss together as a family." Four themes emerged: (a) falling in, (b) hitting bottom, (c) weaving strands to make a rope, and (d) climbing out., Clinical Implications: From their stories, fathers provide insight useful to nurses assisting families of colicky infants through a very difficult time. Nurses should talk to fathers directly about the possibility of colic, and teach both parents what it is, how long it usually lasts, and what can be done about it. Anticipatory guidance as well as discussion about colic during newborn health visits can help parents to vocalize their feelings, and learn what actions to take when the stress of colic becomes overwhelming.

The objective of this study is to determine whether advice in parenting magazines reflects current evidence-based understanding of early infant crying and colic, where (1) "colic" is the upper end of a spectrum of crying behavior reflective of normal infant development, and (2) physical abuse--in particular, shaken baby syndrome (SBS)--is a serious medical consequence of early crying. All available issues of 11 popular Canadian parenting magazines published between January 2000 and December 2004 were hand-searched and systematically reviewed. Fifty-one articles were found with information on: (1) causes of, (2) responses to, and/or (3) mention of SBS or abuse as a consequence of crying and/or colic. There were 105 specific causes suggested, but almost no agreement concerning the causes of crying and colic. Similarly, there were 231 specific responses to crying and colic mentioned, but little agreement among the suggested responses. For both crying and colic together, the consequence of abuse was mentioned only 7 times, and SBS only twice. Making the advice literature a truly helpful vehicle for parents concerning normal behavioral development and its consequences for their new infant seems to be a significant challenge. Arguably, this is an important shared responsibility of physicians, researchers, and journalists.

Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls) matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001), anxiety trait (P = 0.005) and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62). The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002) and depression (P < 0.001) and the number of recurrent colic episodes (anxiety-state: P = 0.016 and anxiety-trait: P < 0.001). These data suggest an association between recurrent renal colic and symptoms of both anxiety and depression.

Michel de Montaigne, the great French humanist and inventor of the personal essay, suffered from frequent and severe renal colic. He wrote about his illness in his travel journal and in his last and greatest essay, "Of Experience." In his illness narratives, Montaigne integrated disease and suffering into his life and art. He humanized rather than conquered his disease. A mature humanism replaced his youthful Stoic philosophy of detachment and disengagement and provides a worthy model for our own medical humanism.

Purpose: There is strong evidence concerning the influence of life event stress on the onset and course of painful acute episodes in primary care. However, few studies have analyzed stressful life events in painful recurrent episodes of renal stone disease. We evaluated the association between painful recurrent colic of renal lithiasis and stressful life events., Materials and Methods: We performed this case-control study in a primary care setting. Study participants were 194 subjects (97 cases and 97 controls) matched according to age and gender. Cases were outpatients with a confirmed diagnosis of nephrolithiasis. The control group consisted of patients seen at the Ophthalmology Outpatient Clinic of the University Hospital, reporting only refraction symptoms and presenting no chronic or acute pathology. Main outcome measures reported were stressful life events as measured by the Social Readjustment Rating Scale., Results: The mean Social Readjustment Rating Scale of cases was significantly higher than controls at 257.56 (+/-193.81) vs 144 (+/-131.24), respectively. Logistic regression revealed that belonging to the case group increased the chances of showing positive results on the scale greater than or equal to 100 (OR 3.02, 95% CI 1.64-5.59) and the chance of presenting results of 200 or greater was 2.87 (OR 2.87, 95% CI 1.58-5.22)., Conclusions: Stressful life events were significantly greater among cases than controls.

Context: Infant crying can cause parental distress, and colic is associated with low maternal self-efficacy and heightened risk for depression. Breastfeeding is recognized as an effective method of calming infants, but the relationship of colic and the use of breastfeeding to remedy infant crying have not been tested for any effects on breastfeeding duration., Objective: To evaluate the effects of infant colic (colic analysis) and breastfeeding as a method of infant calming (calming analysis) on breastfeeding duration., Design: The authors followed 700 healthy breastfeeding mother-baby dyads from birth to 1 year. Maternal interviews were conducted postpartum, and at 2, 5, 10, 16, 24, 38, and 52 weeks to ascertain demographic factors, infant crying patterns, comforting practices, physician-diagnosed colic, and breastfeeding behaviors. Cox survival analyses were used to evaluate the independent effects of: (a) physician diagnosed colic; and (b) breastfeeding as a comforting practice on breastfeeding duration. Data from all 700 breastfeeding dyads were used in the colic analyses. In the calming analyses, to assure that breastfeeding was appropriately established, data were used from the 617 couplets that had breastfed for at least 2 weeks. Using a stepwise process, models, adjusted for typical predictors of breastfeeding duration, were developed for exclusive, full and partial breastfeeding duration. Variables of interest (i.e., colic diagnosis, breastfeeding for comfort) were then forced into the baseline models to determine any independent effects., Results: In the first 16 weeks, parents found that holding (87%), breastfeeding (82%), walking (67%), and rocking (63%) were highly effective calming practices. Mothers who rated breastfeeding as highly effective had a higher frequency of breastfeeding at all contacts (p < 0.05). In adjusted analyses the use of breastfeeding to comfort infants was a significant predictor of longer partial (overall) ([hazard ratio] HR = 0.6, 95% CI 0.4 to 0.9; p = 0.02) but not exclusive or full breastfeeding duration. By 6 months, 44 mothers (6.3%) reported a diagnosis of colic. Mothers of infants with a diagnosis of colic were less likely to report breastfeeding as effective method of infant comforting (p = 0.03). In adjusted analyses the authors found that a diagnosis of colic predicted shorter full breastfeeding duration (HR = 2.4, 95% CI 1.4 to 4.2; p = 0.001) but not exclusive or partial duration., Conclusions: Breastfeeding to comfort a crying infant is a strong predictor of partial (overall) duration and is rated as a highly effective calming method by parents. These data suggest that parents may benefit from education about normal infant crying patterns and effective methods of infant comforting, including breastfeeding. However, mothers of infants diagnosed with colic are at risk for shortened duration of full breastfeeding. Although the reasons for this are unclear, it may be helpful to specifically address the subject of colic and infant feeding and encourage mothers to fully breastfeed for the recommended 6 months.

Excessive crying and fussing in young infants, often called "infantile colic", is a common and often serious problem for parents. It is also associated with infant sleep disturbance and possible disruptions in family life. As such, parents may undertake a variety of actions to stop excessive infant crying, some of which may be detrimental to infant health (e.g., physical shaking). Despite its potentially substantial negative health consequences, there remains no consensus regarding a definitive definition of excessive crying. Available definitions mostly focus on infant crying duration and its effect on parents. A number of different definitions, measurements, causes of crying, and settling management are presented in this article to help foster an understanding of this issue among nurses and to assist parents to cope effectively.

In this open, controlled, prospective study, 28 infants with colic were randomized to either cranial osteopathic manipulation or no treatment; all were seen once weekly for 4 weeks. Treatment was according to individual findings, and administered by the same practitioner. Parents recorded time spent crying, sleeping and being held/rocked on a 24-hour diary. A progressive, highly significant reduction between weeks 1 and 4 in crying (hours/24h) was detected (P<0.001) in treated infants; similarly, there was a significant improvement in time spent sleeping (P<0.002). By contrast, no significant differences were detected in these variables for the control group. Overall decline in crying was 63% and 23%, respectively, for treated and controls; improvement in sleeping was 11% and 2%. Treated infants also required less parental attention than the untreated group. In conclusion, this preliminary study suggests that cranial osteopathic treatment can benefit infants with colic; a larger, double-blind study is warranted.

Background: Caring for an infant with unexplained, persistent crying is one of the most stressful events for new parents. Infant irritability, also referred to as infantile colic, occurs in 10-25% of all infants and is the most common parental concern reported in the first year of life., Objective: The aim of this study was to evaluate the effectiveness of a home-based nursing intervention in reducing parenting stress in three groups of families with irritable infants, using data from a larger evaluation study., Methods: A two-site, randomized clinical trial was conducted with 121 infants and their parents. Infants were randomized to a treatment or a control group. A third group of infants (n = 43) was added as a posttest-only comparison. The level of parenting stress was measured by the Parenting Stress Index (PSI) at baseline, after the 4-week intervention, and at the 8-week follow-up visit., Results: A repeated measures analysis of variance (ANOVA) was used to compare the two groups across the three time points (baseline, immediately after the 4-week intervention, and at the 8-week follow-up visit). The results revealed a reduction in total parenting stress over time for both the treatment and control groups. Mothers in the treatment group reported reduced parenting stress on the parent-child dysfunctional interaction subscale (p = .04). Total parenting stress scores were found to be significantly higher for mothers in the posttest-only group (p = .009)., Conclusion: Initial parenting stress levels were high in all participants. Parent feedback at the exit interview indicated that the nurse visits for data collection were also viewed as helpful in reducing the stress level associated with parenting these irritable infants. This home-based program was perceived as helpful in improving the interactions between parents and their irritable infants.

Purpose: To describe the experience of families with previously colicky infants., Study Design: This qualitative, descriptive study explored parents' perspectives of the lasting effects of infant colic on their children's development and on their family relationships., Methods: Through in-depth interviews, the parents had the opportunity to share what they remembered most about this experience. Participants volunteered by accessing the Infant Colic Study Web site advertised on numerous search engines. Forty-four participants, all of whom had an infant with colic at some time in the past, answered open-ended questions regarding their feelings about the colicky period and how their children developed later. Data were analyzed from a phenomenologic perspective., Results: The majority of participants reported no later problems in their previously colicky children. Some did believe, however, that family relationships had been affected by the colic experience, and that communication and support had been impaired. Most described feelings about the colic experience that were negative., Clinical Implications: Continued support needs to be provided to families of colicky infants throughout their growth and development at a primary care level. Nurses need to recognize that the experience of infant colic may have residual effects on the entire family unit. These families need to be provided with the support and resources to enable them to successfully care for their children and to engage in nurturing relationships.

Aims: A study was undertaken to assess the impact of psychological, psychosocial and socioeconomic factors on the risk of having a child with infantile colic., Methods: Psychosocial and psychological factors were assessed by self-administered questionnaires in the 17th, and by telephone interviews in the 35th-37th pregnancy weeks; infantile colic occurrence was assessed by telephone interviews at infant age 5 weeks; subjects were 1,099 mother-infant dyads., Results: High trait anxiety increased the colic risk; OR 2.04 (95% CI: 1.16, 3.59), and so did affirming a perceived risk of spoiling young infants with too much physical contact; OR 1.77 (1.07, 2.91). In the final step of a multivariate model, not cohabiting with the child's father was the factor with the strongest association with colic; OR 3.48 (1.38, 8.77). Analyses of effect modification showed that high education seemed to protect from the influence of high trait anxiety. Young women were particularly high in trait anxiety, and being exposed to both these risk factors seemed to act synergistically on the risk of having a colicky infant; OR 2.41 (1.12, 5.18)., Conclusions: Psychological and psychosocial factors were found to be significantly related to an increased risk for infantile colic, and these factors interacted with age, parity, social support, and educational level in a complex manner. Even though no single most important psychosocial risk factor was identified, the findings lend support to the strategy of offering special attention in terms of information and support in the maternal healthcare system to very young women, women who do not cohabit with the father, and women with high trait anxiety.

Background: Long term studies of cognitive development and colic have not differentiated between typical colic and prolonged crying., Objective: To evaluate whether colic and excessive crying that persists beyond 3 months is associated with adverse cognitive development., Design: Prospective cohort study. A sample of 561 women was enrolled in the second trimester of pregnancy. Colic and prolonged crying were based on crying behaviour assessed at 6 and 13 weeks. Children's intelligence, motor abilities, and behaviour were measured at 5 years (n = 327). Known risk factors for cognitive impairment were ascertained prenatally, after birth, at 6 and 13 weeks, at 6, 9, and 13 months, and at 5 years of age., Results: Children with prolonged crying (but not those with colic only) had an adjusted mean IQ that was 9 points lower than the control group. Their performance and verbal IQ scores were 9.2 and 6.7 points lower than the control group, respectively. The prolonged crying group also had significantly poorer fine motor abilities compared with the control group. Colic had no effect on cognitive development., Conclusions: Excessive, uncontrolled crying that persists beyond 3 months of age in infants without other signs of neurological damage may be a marker for cognitive deficits during childhood. Such infants need to be examined and followed up more intensively.

Aims: To examine the relation between colic and feeding difficulties and their impact on parental functioning for a primarily clinic referred sample., Methods: Forty three infants (and their mothers) were enrolled between 6 and 8 weeks of age. Infants were divided into two groups, colic (n = 19) and comparison (n = 24), based on a modified Wessel rule of three criteria for colic. Families were assessed at two visits; one occurred in the laboratory and one occurred in a paediatric radiology office. Outcome measures included the clinical assessment of infant oral motor skills, behavioural observation of mother-infant feeding interactions, maternal questionnaires on infant crying, sleeping and feeding behaviours, and the occurrence of gastro-oesophageal reflux (GOR) in the infants using abdominal ultrasound., Results: Infants in the colic group displayed more difficulties with feeding; including disorganised feeding behaviours, less rhythmic nutritive and non-nutritive sucking, more discomfort following feedings, and lower responsiveness during feeding interactions. Infants in the colic group also had more evidence of GOR based on the number of reflux episodes on abdominal ultrasound as well as maternal report of reflux. Mothers in the colic group reported higher levels of parenting stress., Conclusions: Results provide the first systematic evidence of feeding problems in a subgroup of infants with colic. Data also illustrate the impact of these difficulties on parental and infant functioning. The association between feeding difficulties and colic suggests the potential for ongoing regulatory problems in infants presenting with clinically significant colic symptoms.

Unexplained crying in infants aged 1 to 3 months is a common concern for Western parents and health services. This study examined the hypothesis that the crying is due to high infant responsivity, and provides evidence about the types of stimulation that trigger crying in infants who present with high responsivity. The sample included 93 eight-day-old infants from a community sample (47 females, 46 males; mean birthweight 3457g; mean gestation 39.4 weeks; mean Apgar scores 8.28 at 1 minute and 9.59 at 5 minutes). Infants were tested for their response to two standard, mildly challenging, procedures: a neurobehavioural test involving undressing, putting down, and handling, and the Guthrie test, involving a painful heel prick to obtain a blood sample. The infants' crying over 24 hours was recorded in parental diaries. Newborn infants who exhibited high responsivity during the neurobehavioural assessment cried, rather than fussed, the most at home. High responsivity during the neurobehavioural assessment also predicted those infants who cried a lot and met a definition of 'colic' at home. The findings support the responsivity hypothesis and show that infants with high responsivity are upset by undressing, putting down, and sustained handling. Explanations for this and implications for the management of infant crying and colic are discussed.

Human growth in early life has major implications for fitness. During this period, the mother regulates the growth of her offspring through placental nutrition and lactation. However, parent-offspring conflict theory predicts that offspring are selected to demand more resources than the mother is selected to provide. This general issue has prompted the development of begging theory, which attempts to find the optimal levels of offspring demand and parental provisioning. Several models have been proposed to account for begging behavior, whether by biochemical or behavioral pathways, including: (1) blackmail of parents; (2) scramble competition between multiple offspring; (3) honest signaling of nutritional need; and (4) honest signaling of offspring worth. These models are all supported by data from nonhuman animals, with species varying according to which model is relevant. This paper examines the evidence that human suckling and crying signal nutritional demand, need, and worth to the mother. While suckling provides hormonal stimulation of breast milk production and signals hunger, crying fulfills a different role, with evidence suggesting that it signals both worth and need for resources (nutrition and thermoregulation). The role of signaling in nutritional demand is examined in the context of three common health problems that have traditionally been assumed to have physiological rather than behavioral causes: excess weight gain, failure to thrive, and colic. The value of such an evolutionary approach lies in its potential to enhance behavioral management of these conditions.

The ancient Greeks were the first to mention infant colic in recorded history; yet in 2002, the cause of infant colic is still unknown. Review of the infant colic literature suggests there are at least five possible explanations-cow's milk/soy protein allergy or intolerance; immature gastrointestinal system; immature central nervous system; difficult infant temperament; and parent-infant interaction problems consisting of either the transfer of parental anxiety to the infant or the inability of the infant to give clear cues about needs to the caregiver. It is likely the cause of infant colic is multifactorial because it has proven to be so elusive. One or more of the above explanations (or as yet an undiscovered explanation) is likely to play a role in the development of colic in a given infant. Determining the most probable explanation for each infant and then selecting interventions based on this explanation is likely to be more successful in preventing or decreasing the length or frequency of episodes than the various trial-and-error approaches to treatment currently recommended by healthcare providers. Infant colic is an important clinical problem that is amenable to nursing intervention.

The purpose of this study was to compare 40 six- to eight-year-old children, 20 with prospectively ascertained infantile colic and a matched sample of 20 without colic, on characteristics of emotional regulation and on parent stress. Children completed tests of cognitive ability, and mothers completed childhood behavioral questionnaires and a parenting stress assessment. Children with colic had maternal ratings suggestive of more difficulty with emotional regulation than their noncolic matches and displayed a more impulsive cognitive style. However, the mean scores of both groups were in the normal range., (Copyright 2003, Elsevier Science (USA). All rights reserved.)

Background: Colic is widely believed to remit by 3 months of age, with little lasting effect on the infant or the family., Objectives: To determine the prevalence of colic at 3 months and the proportion of cases of colic (identified at 6 weeks) that remitted by 3 months; to identify the factors predictive of colic's remission; and to explore the potential lasting effects of colic on maternal mental health., Design: Prospective cohort study of 856 mother-infant dyads. Self-administered questionnaires were mailed to mothers at 1 and 6 weeks and 3 and 6 months post partum. Standardized instruments were incorporated into the first and last questionnaires to assess maternal anxiety, postnatal depression, and social support. At 6 weeks and at 3 months, mothers completed the Barr diary and/or the Ames Cry Score., Results: Data from 547 dyads were available for analysis. The prevalence of colic at 3 months was 6.4%. More than 85% of cases of colic had remitted by 3 months of age. These infants were more likely to be female, whereas the mothers of these infants were more likely to have received pain relief during labor/delivery and to have been employed during pregnancy. Reductions in scores for trait anxiety and postnatal depression, although smaller for mothers whose infants were colicky at 6 weeks of age, were not significantly different from those of mothers whose infants were never colicky., Conclusion: This study provides support for the belief that, in most cases, colic is self-limiting and does not result in lasting effects to maternal mental health.
