To determine the occurrence of infantile colic and its seasonal variation in an unselected population and to evaluate the amounts of crying in colicky infants and noncolicky controls.
Questionnaire survey and a prospective substudy of parental diaries of crying.
All families with a full-term, healthy-born infant in the Turku City (Finland) district during 1 year.
Colic was defined as paroxysms of crying for 3 or more hours per day for 3 days or more per week during a period of at least 3 weeks. The questionnaires containing this definition were distributed to 1221 families in postpartum wards, and an invitation to a prospective follow-up study was presented to the families if their infant showed colicky symptoms. The incidence questionnaire was to be returned after 3 months. Six hundred four (49%) of the questionnaires were returned, and an additional 355 (29%) families were reached by phone. A total of 59 families with a colicky infant enrolled in the prospective substudy when the infants were at a median age of 5 weeks; age-matched controls were invited from the same population.
The incidence of infantile colic was 13%; possible infantile colic was 8%. No seasonal variation was found. The mean amount of total crying was 241 min/d (95% confidence interval [CI], 216 to 266 minutes) in the colic group and 112 min/d (95% CI, 95 to 130 minutes) in the control group during the first recording week. The mean amount of colicky crying was 122 min/d (95% CI, 102 to 142 minutes) in the colic group and 19 min/d (95% CI, 12 to 26 minutes) in the control group.
The incidence of colic was 13% with no seasonal variation. Parental perception of infantile colic correlated well with the amount of crying.
确定未筛选人群中婴儿腹绞痛的发生率及其季节性变化，并评估腹绞痛婴儿与非腹绞痛对照婴儿的哭闹时长。
问卷调查以及对父母记录的婴儿哭闹情况进行前瞻性子研究。
芬兰图尔库市某区一年内所有生育足月健康婴儿的家庭。
腹绞痛定义为在至少3周的时间内，每周发作3天或以上，每天哭闹3小时或更长时间。将包含此定义的问卷分发给产后病房的1221个家庭，如果其婴儿出现腹绞痛症状，会邀请这些家庭参与前瞻性随访研究。发病率问卷需在3个月后返还。共收回604份（49%）问卷，通过电话联系到另外355个（29%）家庭。共有59个有腹绞痛婴儿的家庭参与了前瞻性子研究，这些婴儿的中位年龄为5周；从同一人群中邀请了年龄匹配的对照婴儿。
婴儿腹绞痛的发生率为13%；可能患有婴儿腹绞痛的比例为8%。未发现季节性变化。在第一个记录周，腹绞痛组婴儿每天的总哭闹时长平均为241分钟（95%置信区间[CI]，216至266分钟），对照组为112分钟（95%CI，95至130分钟）。腹绞痛组婴儿每天腹绞痛哭闹的平均时长为122分钟（95%CI，102至142分钟），对照组为19分钟（95%CI，12至26分钟）。
腹绞痛的发生率为13%，无季节性变化。父母对婴儿腹绞痛的认知与哭闹时长密切相关。
