The number of Latino immigrant children is expanding rapidly, and the factors that affect their health are multiple and interlinked. We therefore propose to describe the sociodemographic characteristics of a mostly Dominican immigrant population, to examine to what extent immigrant status and other factors play a role in determining measures of their children's health and well-being, and finally to investigate whether a home visiting intervention modified any of these factors. The data were collected as part of an evaluation of a primary prevention home visitation program for high-risk mothers and their children. Bivariate and multivariate models were constructed to investigate the factors that affected the outcome variables. We found that numerous factors, especially a composite for overall stress, affected the health and well-being of participant children. We also demonstrated that the visitation program had a positive effect on many of these outcomes. Future program planners will need to understand the strengths and weaknesses of the specific population they serve.
Between 1990 and 1997 the number of children in immigrant families grew by 47 percent, while the number of US-born children grew by only 7 percent. [
Some factors affecting the health of immigrant children have been recognized for decades. One phenomenon is the often described epidemiologic paradox in which infants born to immigrant mothers have better birth outcomes, including fewer preterm births and higher birth weights than native born children, even after taking into account socioeconomic differences [
Since the sociodemographic variables that affect the health of each distinct immigrant population are likely to be different, it is important to try to understand them. Understanding the complex interactions between beneficial and detrimental factors is important in trying to develop health interventions that will ultimately be successful in improving the health of children in immigrant families and in heading off the decline in health indicators that occurs with successive generations (i.e., the epidemiologic paradox). It is also becoming clearer that many of the detrimental factors may work by increasing psychosocial stress [
We therefore propose to describe the sociodemographic characteristics of one mostly Dominican immigrant population in New York City. While this population was selected for mothers at risk, it is fairly representative of the overall community from which it was drawn. Further, we examine to what extent immigrant status and other factors play a role in determining certain measures known to affect childhood health and well-being: breastfeeding, use of the pediatric emergency room for urgent conditions, having a primary care provider, and performance on a developmental screening tool (Ages and Stages Questionnaire). Finally, we examine whether a home visiting intervention designed to address psychosocial stressors modified any of the factors.
The data presented in this paper were collected as part of the Randomized Controlled Trial Evaluation of Best Beginnings, a primary prevention home visitation program in Washington Heights, based on the Healthy Families America Home Visiting program, that has been described previously [
Eligible participants were randomly assigned to either an intervention or a control group. The details regarding the intervention and control groups have been described previously [

In order to investigate whether immigrant status affected childhood health, we examined several independent variables related to immigration status of the children’s mothers: whether or not the mother was born outside the USA as a dichotomous variable (born in USA, not born in the USA), years in the USA as a continuous variable, years in USA as a dichotomous variable (less than or equal to 2 years, 3 years or more), and English proficiency. English proficiency was derived from the Intake Form, in response to the item English Fluency: Adequate or Needs Interpreter. An Acculturation Composite score was calculated by summing
The outcome variables that were investigated were exclusive breast feeding in the first week of life as a dichotomous variable (yes, no), the number of pediatric emergency department (PED) visits from birth to 36 months for all conditions and particularly for urgent conditions for all children making at least 1 PED visit (checked by reviewing PED charts), having a primary care provider at intake and 24 months, and performance on the Ages and Stages Questionnaire (ASQ) at 12 and 24 months. The ASQ is a parent-report measure on infant developmental status that is widely used as a screening tool for detecting developmental delay. Although the ASQ is designed in such a way that the parent actually tests the child, in the present study it was administered with the guidance of the FSW. ASQ items yield subscale scores for 5 domains (Communication, Gross Motor, Fine Motor, Problem Solving, and Personal/Social Functioning). Each domain has 6 questions scored as follows: Yes: 10, Sometimes: 5, Not Yet: 0. Thus at each administration, the total score if all items in a given domain (e.g., Communication) were passed would be 60 for that domain. It was completed at specified intervals during a home visit with the FSW present.
We also assessed families at regular intervals using a measure of maternal/family problems. This is a scale that lists a number of problems or issues that families often face. The participant was asked whether each item was currently an issue for her, at intake, and at each follow-up visit. This was a continuous variable with the mother receiving a point for each item she answered yes to, with a maximum possible score of 15
Sociodemographic variables were calculated as means or percentages and were presented separately for the intervention and control groups and the total sample. Bivariate and multivariate tests were done to investigate the association between different measures of immigration status and outcome variables, using either simple regression analysis or Spearman’s
The socio-demographic characteristics of the overall population are described in Table
The first outcome variable that was examined was exclusive breastfeeding in the immediate postpartum period (up to 7 days after birth). We tested for the significance of an association between 14 socio-demographic variables (including infant gender), and breastfeeding. The only factors positively associated with exclusive breastfeeding on bivariate analysis were fewer years in the US, higher education level of mother, biological father as second primary caregiver, and birth weight not less than 5.5 pounds at birth. When a multivariate logistic regression analysis was conducted entering all of the factors significant on bivariate analysis, only exposure to the prenatal intervention and mother having at least a high school education remained significant (Table

The second set of outcome variables examined focused on utilization of the PED (Table

The second outcome variable was the number of PED visits for urgent conditions. The factors that were significantly associated with a higher number of urgent PED visits on bivariate analysis were participation in the intervention, younger age of child at first PED visit, mother born in the USA, and birth weight of child less than 5.5 pounds. In the multivariate analysis, birth weight was no longer a significant contributor.
At intake, the percentage of mothers in the total sample with a primary care provider (PCP) was 90%. Among postnatally enrolled mothers there was a significant interaction between parity and immigration status (results not shown). Among multiparous mothers, only 50% (10/20) of those with less than 2 years in the US had a PCP at intake as compared to 78% (65/83) of those with 3 or more years in the US. Conversely, among primiparous mothers, 93% (14/15) of those with less than 2 years living in the US had a PCP, as compared to 88% (57/65) of those with 3 or more years in the US.
At the 24-month followup, among prenatally enrolled mothers, significantly more intervention group mothers (89%) had PCPs than control group mothers (75%). Among postnatally enrolled mothers, the difference was not significant (intervention group = 77%; control group = 73%).
The overall composite score on the ASQ at 12 months and 24 months of age was examined in a multiple regression analysis with a number of predictor variables that were significant on bivariate analysis. The results are shown in Table

The intervention had a positive effect on a number of the previous variables. Prenatal participation in the intervention was significantly associated with more exclusive breastfeeding post-delivery. Participation in the intervention was significantly positively associated with both overall and urgent PED visits. The intervention obviously did not affect the percentage of mothers with PCPs at intake, but by 24 months among prenatally enrolled mothers significantly more intervention than control group mothers had PCPs [
The results of this study indicate that there are many factors that may affect the health and well-being of children in this largely Dominican, immigrant population. This study population is subject to many stressors, which is reflected in several of the measures. The mean score on the Kempe Family Stress Inventory (KFSI) in this population is 34, which indicates that the families are at psychosocial risk for poor parenting and are experiencing a great deal of family stress. Though the program recruited families who were at high psychosocial risk, 96% of the overall population (1,400 of 1,459) from which they were drawn initially screened positive on a Short Initial Screen for psychosocial risk. Also, on the subsequent Kempe Family Stress Inventory, 93% (674/724) of all those screened received a score of 25 or higher. These results include those enrolled in the study and those not enrolled. This is indicative of the stress level of the overall community and indicates that the study participants are representative of the overall population. Socio-demographic variables for the participant group and for the larger community demonstrate a low level of education and English proficiency and limited financial resources. These are all factors which we would expect from previous studies to negatively affect the health of the children in this population.
Despite the high level of stressors in this community, the health indicators for the community, in many instances, compare favorably to the rest of New York City (NYC). The 2003-2004 heart disease death rate in Washington Heights/Inwood was 222/100,000, compared to the NYC overall rate of 297/100,000 and the average annual death rate for people under 75 was 10% lower than that for NYC overall (640 versus 718/100,000) [
Newly arrived immigrants may be expected to access healthcare less often due to financial, language, and cultural barriers. One study of children in California showed that immigrants were more likely to lack insurance and postpone emergency room visits because of this [
Length of time in the USA had a strong effect on likelihood of having a PCP but only for those who had more than one child at the time of enrollment in the program. Mothers who were having their first baby had high rates of having a PCP regardless of length of time in the US—93% for the group in the US less than 2 years and 88% for the group in the US 3 or more years. But for multiparous mothers those in the US for less than 2 years had a PCP at enrollment only 50% of the time, compared to 78% for those there longer. This is an area that requires further study.
Immigrant children may be at greater risk for cognitive delays because of psychosocial stress [
We examined whether a home visitation program that provided support and guidance to families and offered services directed to alleviating many of these stressors could have an impact on childhood health and well-being. The program does seem to have made a difference in several areas, including increasing PED usage and improving ASQ scores at 24 months for male children. Appropriate use of the medical system was explained to the intervention group who seemed to learn to use the primary care system more appropriately, going to the PED after calling the primary care office first. Another significant finding is that the intervention was positively associated with exclusive breastfeeding, even after controlling for years in the USA. These are important findings. While immigrant families arrive with many protective health behaviors, we need to prevent the worsening of various health indicators with successive generations of Latino immigrants.
The intervention was not successful in all areas and success was sometimes not apparent until 2 years into the intervention. Although it did positively affect development as measured by ASQ scores, this did not become evident until 24 months. Many of the components of the maternal/family problems scale were not affected, such as financial, housing, and domestic violence issues. The FSWs linked both the intervention and control group families to primary care providers. However, the FSWs reinforced this link for the intervention group. Only at 24 months was the percentage of intervention group families with PCPs higher than the percentage for the control group.
This study adds to the evidence describing the many factors which can and do affect the health of immigrant children. We found that a composite for overall stress, maternal/family problems, which is very high in this population and in many immigrant populations, was the strongest predictor of developmental outcomes. Psychosocial stress has been shown to be an important factor in the health of other immigrant populations as well [
This study had a number of limitations. One of its strengths was that it investigated a particular, mostly Dominican Latino population in northern Manhattan. This is also a weakness in that it is hard to comment on the generalizability of these results to other specific immigrant populations. Also, this study only investigated a small number of health indicators for immigrant children, and there are many other relevant factors that need to be investigated.
