■目的是确定儿童从出生到生命两年的体重和身长的轨迹模式,并建立与母婴特征的关联。
■在科伦坡PR的公共卫生服务中进行了一项混合队列研究,巴西,2018年至2022年。通过人体测量数据收集和问卷调查收集妊娠信息。出生数据是从出生记录表中提取的,而出生后头两年的体重和身长数据是从身体和电子健康服务记录中获得的。使用基于组的轨迹模型识别重量和长度轨迹模式。要选择的轨迹模式的数量的定义考虑了适合变量类型的模型,它的实用性,以及组成员的概率。
■在儿童中确定了体重和长度的两种轨迹模式。大多数人表现出体重模式(67.8%,n=382)和长度(90.9%,n=472)被认为是高且稳定的,从一岁半开始减速的趋势。属于低体重增加组的概率与女性相关(41.5%,p<0.001),怀孕期间吸烟(48.7%,p=0.008),早产(65.0%,p=0.001),剖宫产(36.4%,p=0.009),小于胎龄(69.0%,p<0.001),和孪生(69.2%,p=0.002)。同样,属于较低长度增益组的概率与女性相关(11.7%,p<0.001),怀孕期间吸烟(20.6%,p=0.003),剖宫产(10.1%,p=0.048),出生小于胎龄(46.4%,p<0.001),和孪生(46.1%,p<0.001)。
■怀孕和分娩期间的状况会影响生命最初两年的生长模式。
UNASSIGNED: The aim was to identify trajectory patterns of weight and length in children from birth until two years of life and establish associations with maternal and child characteristics.
UNASSIGNED: A mixed-cohort study was conducted in public health services in Colombo-PR, Brazil, between 2018 and 2022. Pregnancy information was gathered through anthropometric data collection and questionnaires. Birth data were extracted from birth record forms, while weight and length data in the first two years of life were obtained from physical and electronic health service records. Weight and length trajectory patterns were identified using a group-based trajectory model. The definition of the number of trajectory patterns to be selected considered the model fit to the type of variable, its practical utility, as well as the probabilities of group membership.
UNASSIGNED: Two trajectory patterns of weight and length were identified among the children. The majority exhibited a pattern of weight (67.8%, n = 382) and length (90.9%, n = 472) considered high and stable, with a tendency to decelerate from one and a half years of age. The probability of belonging to the lower weight gain group was associated with female sex (41.5%, p < 0.001), smoking during pregnancy (48.7%, p = 0.008), prematurity (65.0%, p = 0.001), cesarean delivery (36.4%, p = 0.009), small for gestational age (69.0%, p < 0.001), and twinning (69.2%, p = 0.002). Similarly, the probability of belonging to the lower length gain group was associated with female sex (11.7%, p < 0.001), smoking during pregnancy (20.6%, p = 0.003), cesarean delivery (10.1%, p = 0.048), born small for gestational age (46.4%, p < 0.001), and twinning (46.1%, p < 0.001).
UNASSIGNED: Conditions during pregnancy and childbirth can impact growth patterns in the first two years of life.
