Longitudinal Trajectories of Gestural and Linguistic Abilities in Very Preterm Infants in the Second Year of Life.

The present study involved a systematic longitudinal analysis, with three points of assessment in the second year of life, of gestures/actions, word comprehension, and word production in a sample of very preterm infants compared to a sample of full-term infants. The relationships among these competencies as well as their predictive value on language development at 24 months and the contribution of biological, medical and social risk factors on language delay at 24 months were also analysed. One hundred and four monolingual Italian very preterms (mean gestational age 29.5 weeks) without major cerebral damages, and a comparison group of 20 monolingual healthy Italian full-terms were followed at 12, 18 and 24 months by administering to their parents the Italian short forms of the MacArthur-Bates CDI. Preterms showed a slower acquisition in gesture/action production, word comprehension, and word production with an increasing divergence with respect to full-terms from 12 to 24 months, when 20% of preterms were delayed in word production (<10th percentile) and 14% did not combine words yet. Lexical competencies at 12 months and together with gestures/actions at 18 months were predictive of word production at 24 months, with a stronger contribution of word comprehension at 12 months and of word production at 18 months. Male gender, bronchopulmonary dysplasia, and low maternal educational level increased the risk of language delay at 24 months. Our findings suggest there to be a slower rate of communicative-linguistic development in very preterms with an increasing difference in their gestural and lexical competencies in the second year of life with respect to full-terms. The interplay of the above competencies and biological, medical and social risk factors increase the risk of language delay at 24 months in very preterm infants.

The effect of gestational age on developmental outcomes: a longitudinal study in the first 2 years of life

BACKGROUND Extremely low and very low gestational age (ELGA and VLGA) constitutes a risk factor for development even in absence of cerebral damage, as an immature central nervous system is exposed to invasive and inadequate stimulation. We tested the hypothesis that GA impacts developmental outcomes and trajectories of preterms without major cerebral damage in the first 2 years of life, expecting poorer developmental outcomes and higher rate of impairment with the decreasing of GA. We also evaluated whether GA, together with developmental outcomes in the first year of life, was related to developmental outcomes at 24 months. METHODS Eighty-eight infants, divided into three GA groups (ELGA: ≤28 weeks; VLGA: 29-32 weeks; full term: >37 weeks) were assessed longitudinally at 6, 12, 18 and 24 months using the Griffiths Mental Development Scales. RESULTS Use of a repeated measure multivariate analysis of variance resulted in several significant findings. GA was associated with the developmental quotient (DQ) scores (P= 0.006); and locomotor (P < 0.001), eye and hand co-ordination (P= 0.016) and performance (P= 0.040) sub-scale quotient (SQ) scores; age of evaluation was also associated with DQ scores (P= 0.002), and locomotor (P < 0.001) and performance (P < 0.001) SQ scores. In particular, ELGAs exhibited lower DQ and SQ scores compared with the VLGA and full-term groups; some ELGAs showed mild, moderate or severe cognitive impairments, while few VLGAs mild impairments. Linear regression analysis showed that GA (P= 0.034) and 12-month developmental outcome (P < 0.001) were related to 24-month developmental outcome. CONCLUSIONS Different developmental trajectories emerged in relation to GA, with poorer developmental outcomes and higher rates of impairment in ELGAs and few mild impairments in VLGAs. The relevance of taking into account both GA and repeated assessments in the first 2 years of life was shown.

Pediatrician-led Motivational Interviewing to Treat Overweight Children: An RCT

OBJECTIVE: The aim of this study was to evaluate the effect of family pediatrician–led motivational interviews (MIs) on BMI of overweight (85th ≥BMI percentile ≥95th) children aged 4 to 7 years. METHODS: All the family pediatricians working in Reggio Emilia Province (Italy) were invited to participate in the study; 95% accepted. Specific training was provided. Parents were asked to participate in the trial if they recognized their child as overweight. Children were individually randomly assigned to MIs or usual care. All children were invited for a baseline and a 12-month visit to assess BMI and lifestyle behaviors. The usual care group received an information leaflet, and the intervention group received 5 MI family meetings. The primary outcome was the individual variation of BMI, assessed by pediatricians unblinded to treatment groups. RESULTS: Of 419 eligible families, 372 (89%) participated; 187 children were randomized to MIs and 185 to the usual care group. Ninety-five percent of the children attended the 12-month visit. The average BMI increased by 0.49 and 0.79 during the intervention in the MI and control groups, respectively (difference: –0.30; P = .007). MI had no effect in boys or in children whose mothers had a low educational level. Positive changes in parent-reported lifestyle behaviors occurred more frequently in the MI group than in the control group. CONCLUSIONS: The pediatrician-led MI was overall effective in controlling BMI in these overweight children aged 4 to 7 years, even though no effect was observed in male children or when the mother’s education level was low.

Air pollution from incinerators and reproductive outcomes: a multisite study.

Background: The few studies that have investigated the relationship between emissions from municipal solid-waste incinerators and adverse pregnancy outcomes have had conflicting results. We conducted a study to assess the effects of air emissions from the eight incinerators currently in operation in the Emilia-Romagna Region of Italy on reproductive outcomes (sex ratio, multiple births, preterm births, and small for gestational age [SGA] births). Methods: We considered all births (n = 21,517) to women residing within a 4-km radius of an incinerator at the time of delivery during the period 2003–2010 who were successfully linked to the Delivery Certificate database. This source also provided information on maternal characteristics and deliveries. Each newborn was georeferenced and characterized by a specific level of exposure to incinerator emissions, categorized in quintiles of PM10, and other sources of pollution (NOx quartiles), evaluated by means of ADMS-Urban system dispersion models. We ran logistic regression models for each outcome, adjusting for exposure to other pollution sources and maternal covariates. Results: Incinerator pollution was not associated with sex ratio, multiple births, or frequency of SGA. Preterm delivery increased with increasing exposure (test for trend, P < 0.001); for the highest versus the lowest quintile exposure, the odds ratio was 1.30 (95% confidence interval = 1.08–1.57). A similar trend was observed for very preterm babies. Several sensitivity analyses did not alter these results. Conclusions: Maternal exposure to incinerator emissions, even at very low levels, was associated with preterm delivery.

Motivational Interviewing to Treat Overweight Children: 24-Month Follow-Up of a Randomized Controlled Trial

BACKGROUND: Pediatrician-led motivational interviewing can be an effective way of controlling BMI in overweight children in the short term. Its long-term efficacy is unknown. The primary aim was to determine whether the short-term (12-month) impact of family pediatrician-led motivational interviews on the BMI of overweight children could be sustained in the long term (24 months), in the absence of any other intervention. METHODS: Children were recruited in 2011 by family pediatricians working in the province of Reggio Emilia, Italy, and randomly allocated to receive either 5 interviews delivered over a 12-month period or usual care. Eligible participants were all 4- to 7-year-old overweight children resident in the province of Reggio Emilia who had been receiving care from the pediatrician for ≥12 months. The primary outcome of this study was individual variation in BMI between the baseline visit and the 24-month follow-up, assessed by pediatricians not blinded to treatment group allocation. RESULTS: Of 419 eligible families, 372 (89%) participated; 187 children were randomized to receive intervention and 185 to usual care. Ninety-five percent of the children attended the 12-month follow-up, and 91% attended the 24-month follow-up. After the 12-month intervention period, BMI in the intervention group increased less than in the control group (0.46 and 0.78, respectively; difference −0.32; P = .005). At the 24-month follow-up, the difference had disappeared (1.52 and 1.56, respectively; difference −0.04; P = .986). CONCLUSIONS: The intervention lost its effectiveness within 1 year of cessation. Sustainable boosters are required for weight control and obesity prevention.

Effects of immigrant status on Emergency Room (ER) utilisation by children under age one: a population-based study in the province of Reggio Emilia (Italy)

BackgroundThe primary aim of this study was to assess the effect of immigrant status on Emergency Room (ER) utilisation by children under age one, considering all, non-urgent, very urgent, and followed by hospitalisation visits. The second aim was to investigate the role played by mother’s educational level in the relationship between citizenship and ER utilisation.MethodsThe cohort study included all healthy singleton live births in the years 2008–2009 and residing in the province of Reggio Emilia, followed for the first year of life in order to study their ER visits. The outcomes were the ER utilisation rate for all, non-urgent, very urgent, and followed by hospitalisation visits. The main explanatory variable was mother’s citizenship. Other covariates were mother’s educational level, maternal age, parity, and child gender. Multivariate analyses (negative binomial regression and zero inflated when appropriate) were performed. Adjusted utilisation Rate Ratios (RR) and their 95% Confidence Intervals (95% CI) were calculated. Trend for age in months by citizenship is depicted.ResultsThere were 3,191 children (36.4%) with at least one ER visit in the first year of life. Adjusted RR show a significantly greater risk of ER visit for immigrants than for Italians: (RR 1.51; 95% CI 1.39-1.63). Immigrants also had a higher risk of non-urgent visits (RR 1.72; 95% CI 1.48-2.00) and for visits followed by hospitalizations (RR 1.58; 95% CI 1.33-1.89). For very urgent visits, the immigrants had a slightly higher risk compared to Italians (RR 1.25; 95% CI 0.98-1.59).The risk of ER visits is higher in the first two months of life (RR1stvs 3rd-12th 2.08; 95% CI 1.93-2.24 and RR 2ndvs 3rd-12th 1.45; 95% CI 1.33-1.58, respectively). Considering all visits, the ER utilisation rate was inversely related with maternal education only for Italians (low educational level 44.0 and high educational level 73.9 for 100 children; p value for trend test < 0.001).ConclusionsOur study observed a higher use of ER services by immigrant children and, to a lesser extent, by children of less educated Italian mothers. In immigrants, the excess is mostly due to non-urgent visits and only slightly to high acute conditions.

Assessing quality of life in children and adolescents: development and validation of the Italian version of the EQ-5D-Y

Background : Although assessment of Health Related Quality of Life (HRQoL) in paediatric populations is gaining interest, it is not sufficiently assessed. While a number of specific paediatric instruments have been developed, some users appear to prefer generic tools such as the EQ-5D, which is a widely used and recommended tool to describe and value health across many different adult populations. We adapted the EQ-5D generic instrument into the EQ-5D-Y(youth) for the assessment of HRQoL in children and adolescents, and investigated the feasibility, acceptability, validity and reliability of this new version of the tool. Methods : The Italian version of the EQ-5D-Y was administered to 415 children and adolescents from a general population aged between 8 and 15, and to 25 paediatric patients diagnosed with Acute Lymphoblastic Leukaemia (ALL). Results : The Italian version of the EQ-5D-Y was found to be feasible and acceptable for self-completion in the target age-group, with less than 1% refusing to complete it and no invalid answers given. Convergent and divergent validity tested with a child specific standard instrument was satisfactory overall. The test-retest reliability was moderate to good in all the domains of the descriptive system, and the Visual Analogue Scale (VAS) showed optimal levels of reliability (Intraclass Correlation Coefficient = 0.82). As regards known-group validity, compared with the youths from general population, the ALL patients reported more difficulties in four of the five domains of the descriptive system and, on average, had a lower VAS score. Conclusions :The Italian version of the EQ-5D-Y shows to be a promising tool for assessing HRQoL in children and adolescents from 8 to 15 years of age. Future studies should further investigate and optimize its applicability to clinical research and carry out economic evaluations within the health system.

Exposure to emissions from municipal solid waste incinerators and miscarriages: A multisite study of the MONITER Project

BACKGROUND Miscarriages are an important indicator of reproductive health but only few studies have analyzed their association with exposure to emissions from municipal solid waste incinerators. This study analyzed the occurrence of miscarriages in women aged 15-49years residing near seven incinerators of the Emilia-Romagna Region (Northern Italy) in the period 2002-2006. METHODS We considered all pregnancies occurring in women residing during the first trimester of pregnancy within a 4km radius of each incinerator. Addresses were geocoded and exposures were characterized by a dispersion model (ADMS Urban model) producing pollution maps for incinerators based on PM10 stack measurements and for other pollution sources based on NOx ground measurements. Information on pregnancies and their outcomes was obtained from the Hospital Discharge Database. Simplified True Abortion Risks (STAR)×100 estimated pregnancies were calculated. We ran logistic regressions adjusting for maternal characteristics, exposure to other sources of pollution, and sites, considering the whole population and stratifying by miscarriage history. RESULTS The study analyzed 11,875 pregnancies with 1375 miscarriages. After adjusting for confounders, an increase of PM10 due to incinerator emissions was associated with an increased risk of miscarriage (test for trend, p=0.042). The odds ratio for the highest quartile of exposed versus not exposed women was 1.29, 95% CI 0.97-1.72. The effect was present only for women without previous miscarriages (highest quartile of exposed versus not exposed women 1.44, 95% CI 1.06-1.96; test for trend, p=0.009). CONCLUSION Exposure to incinerator emissions is associated with an increased risk of miscarriage. This result should be interpreted with those of a previous study on reproductive health conducted in the same area that observed an association between incinerator exposure and preterm births.

P I – 1–4 Source-related components of pm2.5 and long-term health effects: epidemiological findings of supersite project in italy

Background/aim Supersite project collected detailed measurements on chemicals, physical and toxicological parameters of atmospheric aerosols in Emilia-Romagna region (Northern Italy) in 2012–2014. Aim of the present study was the assessment of long-term effects of PM2.5 and its sources on natural, respiratory and cardiovascular mortality in an open residential cohort. Methods We built a cohort (age ≥29 years) in 47 municipalities for 2001–2010. We collected mortality data for 2009–2013. 3 year measurements of daily concentration and constituents of PM2.5 were made at 4 sites and were analysed through a Source Apportionment approach identifying 6 sources. For each source, the annual percentage contribution in each site was estimated, and these data were used to estimate exposure, according to both the site and to the yearly average value of PM2.5 at each address, derived from a LUR model. Yearly concentration map from regional dispersion models were also used to consider temporal variations. We used Cox models with time-dependent exposures. Bi-pollutant model was performed, adjusting for the remaining PM2.5 mass, to verify independent effect of each source. Results The cohort includes about 2 million inhabitants (6,011,667 person-years) with 82 624 deaths for natural causes. Identified sources were Traffic, Biomass Burning, Oil Combustion, Anthropogenic Mix; Secondary Nitrates and Secondary Sulfate. We observed an association between PM2.5 total mass and natural mortality (HR=1.007; 95% CI: 1.004 to 1.011 per 1 µg/m3 PM2.5). 1-unit increment of BB and OC were associated with an increased risk of natural mortality, independent from the remain part of PM2.5 (HR=1.015; 95% CI: 1.005 to 1.025 and HR=1.035; 95% CI: 1.005 to 1.065, respectively). Respiratory mortality showed HR comparable to natural mortality (HR=1.008; 0.995–1.020 per 1 µg/m3 PM2.5), while association with cardiovascular mortality were equal to 1.003 (95% CI: 0.998 to 1.009 per 1 µg/m3 PM2.5). Conclusion A large residential cohort was built to examine the long-term impact on mortality of exposure to Source-related components of PM2.5. This study suggests an effect of long-term exposures for some specific sources, both on natural and respiratory mortality indicating a relevant role of Biomass Burning and Oil Combustion. These findings can be useful to orientate the pollution reduction policies

Cohort profile: the Italian Network of Longitudinal Metropolitan Studies (IN-LiMeS), a multicentre cohort for socioeconomic inequalities in health monitoring

Purpose The Italian Network of Longitudinal Metropolitan Studies (IN-LiMeS) is a system of integrated data on health outcomes, demographic and socioeconomic information, and represents a powerful tool to study health inequalities. Participants IN-LiMeS is a multicentre and multipurpose pool of metropolitan population cohorts enrolled in nine Italian cities: Turin, Venice, Reggio Emilia, Modena, Bologna, Florence, Leghorn, Prato and Rome. Data come from record linkage of municipal population registries, the 2001 population census, mortality registers and hospital discharge archives. Depending on the source of enrolment, cohorts can be closed or open. The census-based closed cohort design includes subjects resident in any of the nine cities at the 2001 census day; 4 466 655 individuals were enrolled in 2001 in the nine closed cohorts. The open cohort design includes subjects resident in 2001 or subsequently registered by birth or immigration until the latest available follow-up (currently 31 December 2013). The open cohort design is available for Turin, Venice, Reggio Emilia, Modena, Bologna, Prato and Rome. Detailed socioeconomic data are available for subjects enrolled in the census-based cohorts; information on demographic characteristics, education and citizenship is available from population registries. Findings to date The first IN-LiMeS application was the study of differentials in mortality between immigrants and Italians. Either using a closed cohort design (nine cities) or an open one (Turin and Reggio Emilia), individuals from high migration pressure countries generally showed a lower mortality risk. However, a certain heterogeneity between the nine cities was noted, especially among men, and an excess mortality risk was reported for some macroareas of origin and specific causes of death. Future plans We are currently working on the linkage of the 2011 population census data, the expansion of geographical coverage and the implementation of the open design in all the participating cohorts.
